While the speedruns performed live on stream at Games Done Quick events aren't necessarily the fastest runs in their categories (though world records have been broken), they're often some of the most entertaining. The live audience ups the pressure, and the commentary from the streamers as they explain their ridiculous glitches is always fascinating.

Last week, the latest Awesome Games Done Quick marathon raised over two million dollars for The Prevent Cancer Foundation and gave us many more frame-perfect feats to be awed by. Below are some of our favorite runs from AGDQ 2018 (specifically of games that are on PC, naturally), and we'll have more about the event and its future soon.

Note that you may have to skip ahead a ways in these videos if they don't auto-jump to the beginning of the run. You can see all the runs on AGDQ's YouTube channel.

Resident Evil 7 (1:49:27) 

By Carcinogen

Probably the most widely celebrated speedrun of AGDQ, it's no surprise that we'd want to highlight this incredible Resident Evil 7 run first. It's a perfect entry point into what makes AGDQ special: a talented runner, an informative and funny couch of commentators, and a challenging game that's tense to watch. Carcinogen's run is full of moments where things go wrong and he manages to just barely survive, but it's his charisma that really makes it all fun—like when he takes the piss out of a jumpscare by adding in a scare of his own. —Steven Messner

Wonder Boy: The Dragon's Trap (27:49) 

By tinahacks

Lizardcube's gorgeous remake of Wonder Boy 3 is mostly faithful to the original, and has a retro mode you can activate at any time to see the original graphics. During tinahacks' skilful run she uses that to skip boss intros, and one of the Lizardcube team, who is there on the couch, is just a little bit crushed by it. Having someone who worked on the game there to contribute insights adds a lot to what would already be an impressive speedrun (I played a lot of Wonder Boy 3 on my neighbor's Sega Master System, and I never came close to being as good as tinahacks). Lizardcube are actively involved with the speedrun community, and even decided to leave a few of the more interesting glitches in their remake so runners could exploit them, as you'll see here. —Jody Macgregor

Skyrim (50:26) 

By Wall of Spain

I enjoyed seeing high-skill speedruns like Claris's run of Sonic Mania, but I also like the goofy stuff and Wall of Spain's glitchy tumble from one end of Skyrim to the other was as goofy as they get. He stops to get married (or at least tries to), screws up one of the only fights necessary to finish the main storyline, and makes extreme use of the strange fact that in Skyrim your character's velocity remains constant when you load a different save. You can complain about Bethesda's open-world games being buggy, but without those bugs glorious messes like this wouldn't be possible and speedruns wouldn't be half as fun to watch. —Jody Macgregor

Half-Life: Opposing Force (26:14) 

By alexh0we

It starts slow, but stick with this run to the second chapter where alexh0we starts murdering hapless NPCs to steal their guns, strafe and machinegun boosting, and sticking some brutal jumps. Most interesting from a technical perspective are the framerate tricks—drop it low enough, for instance, and you can walk through lasers because in no frame will they connect with you. Alexh0we's stream of informative commentary keeps this run entertaining even during the slow parts.  —Tyler Wilde

Arabian Nights (47:17) 

By Kotti

The Awful Games block of ADGQ is a gauntlet of nightmarishly terrible games, but none are as baffling or as hilarious as Arabian Nights, an extremely obscure 2001 platformer that tried to cash in on Prince of Persia’s popularity. From start to finish, the run is a confusing mess of inexplicable glitches and terrible game design underscored by Arabian Night’s eye-rolling portrayal of Middle-Eastern culture and Conan the Barbarian-style objectification of women. You have to see it to believe it. Speedrunner Kotti has to endure multiple crashes just to beat the damn thing, but it’s all worth it for the couch commentary and laughably bad cutscenes. —Steven Messner

Left 4 Dead 2 (55:15) 

By mr.deagle, The Master, burhác, and MrFailzzz 

This is a special run in a few ways. Firstly, it's co-op, which you don't see in a lot of speedruns, and secondly, Left 4 Dead 2 isn't going to throw out weapons and zombies in the same way each time, which sets it apart from games that can be perfectly memorized. Yet the zombies are mere pests to these players, who are wholly focused on performing impressively huge skips (which involve a grenade launcher) and bunny hops. Though I could never play as well as this squad does in Left 4 Dead 2, runs like this can reveal how much challenge comes from us buying into a game's premise rather than the game itself. Play Left 4 Dead 2 like a race to master, and the undead are just speedbumps. —Tyler Wilde

Hollow Knight (38:28)

By Mickely3

It's slightly sad to see one of our favorite games of 2017 demolished in under 40 minutes, but Mickely3's run contains some impressive glitching—did you know you can just float around all the time and Hollow Knight is totally fine with that?—as well as just some old fashioned good platforming.  —Tyler Wilde

The internet is vast and full of streams. The prevalence of YouTube and Twitch ensure that more gaming silliness is being captured and shared than ever. People are still doing amazing work with Source's film making tools and The International 7 produced its share of amusing moments. Here are some of the videos and gifs that tickled us this week.

How to stick a landing

Here's how big a deal Doom's shotgun was: in a game with another weapon called the Big Fucking Gun, the shotgun is the one we remember best. It's reliable at practically any distance. One clean shot to the chest will eviscerate most enemies. Somehow that pump action reload animation and its cha-chick are satisfying every single time with only five frames of animation. How many other games are confident enough to give you a gun this good 10 seconds into the first level?

Before Doom, shotguns were for shooting clay pigeons. After Doom, they were for annihilating demons. And for annihilating practically anything else: as Doom birthed a new genre, you could rely on the trusty shotgun to be there almost anytime, more steadfast and reliable than a squirrely pistol or a ammo-hungry rifle. It's our pellet pal. Our blunderbuss buddy. In the wry words of John Romero, when we spent half an hour reflecting on the design and history of Doom's shotgun: "No other game has a BFG 9000 in it, but lots of games have shotguns."

Today we're celebrating that lineage by talking about some of our favorite shotguns and why we love them. Step one: make it kick, and make 'em bleed.

How to make a great shotgun

"Number one, the damage it does is the most important part," said John Romero. He was talking about weapon design in general. There's so much that goes into a good game gun, but those pain points have the biggest impact in making a weapon feel powerful. "If it does more damage than any other gun, it doesn't matter if it has no sound effects, you're going to be using it," he laughed.

OK, but all that other stuff is important too. Animation, sound effects, the works. When they all come together, you can just feel it. It's an almost animal hell yeah. Fullbright's Steve Gaynor practically got poetic describing this sensation:

"Shooter games can be about a lot of things—the complexity of tactics as you use the environment to your advantage, the cat & mouse drama of chasing and being chased, sneaking up on your prey or falling into your enemy's trap—but it's also always about that aesthetic moment where the trigger's pulled and the audiovisual effects deliver that moment of utterly blowing a videogame creature away. And that's what the shotgun's all about. It's loud. It's sudden. And above all, it's effective."

So how do design all that stuff to feel just right? Bill Munk, animator and creative director at Tripwire, had this to say about developing Killing Floor 2: 

"We start with the gore system, which is a very important ingredient that makes shotguns feel devastating. Second is the impulse force applied to the creatures when they get hit, this is really important to not only make the shotgun feel powerful but also adds to the enjoyment of taking down a target. Third is the damage each pellet does, it's a hard balancing act because depending on what you shot, if it doesn't die or react the way you picture it, everything falls apart and the weapon feels unsatisfying. To balance shotguns in KF2 we first start with the price for the ammo, the weight of the gun and the time it takes to reload. Shotguns generally have massive damage but become less effective at range due to the spread of the pellets which also is a nice tool to balance these high damage weapons.

"Last but not least are the shoot animations. This is an area we've put a lot of time and research in. We animate the shots at high framerate so that we can animate the violent force when you fire a shotgun. This is a detail you barely notice in realtime but can feel the difference."

And when Killing Floor 2 slows down into Zed time, you can really see that animation at work.

You can see even more detail in KF2's shotguns firing and reloading here. They're ahead of the curve in animations, but the fact that Doom's shotgun still feels good with only five frames of reload animation shows how much the damage, muzzle flare, sound effects, and other elements of a shotgun can make it feel satisfying without much real detail.

Take Resident Evil 4's starting shotgun, a standard pump action. It's much simpler than Killing Floor 2's weapons, but blasting zombies with it feels a bit like smiting them with the fist of God. Part of that comes from RE4's once-novel over-the-shoulder weapon aiming. It's incredibly physical. You hold a button down to aim and Leon plants his feet. The camera zooms up to his shoulder, and it feels like you're aiming the shotgun with the whole of his body. The muzzle jerks sharply upward when you fire, and a single blast can send a whole crowd flying backwards. Leon pumps out the spent shell before recentering his aim. It's not fancy, but it feels sublime.

Sound off

No game gun sounds more pleasing to the ear than a shotgun except for, maybe, a bolt-action rifle. And those two weapons have something in common: both are about a single moment of release, followed by a peerless sound saying fire again, baby.

Most game weapons are about a constant stream of sound. The blam, blam, blam of a pistol, the ratatatat of an SMG, the heavy thugthugthugthug of an LMG. With a shotgun, it's all about that one shot. It's a crack of thunder, not a boom. "You need a good, sharp, aggressive sound to drive the shotgun's presence home, not some underplayed thud but a good, bracing crack," said Gaynor.

But the reload can be even better. Only a heavy bolt can match the click of a double barrel popping open and closed or the cha-chick of the pump action. That sound effect really hasn't changed much since Doom 1, and it's easy to see why.

Sound is a big part of why we love shotguns, but it's also crucial to the "feel" of hower powerful they are. "I'd say sound is 70% of the feel of a great shotgun mostly because I've played games while they are muted and they lost the feel," said Kynan Pearson, who's worked on the Halo and Metroid Prime series. "The reload noise, the boom and the pain noises create a fantastic symphony of death."

Producer Matt Powers, who worked as a producer on the Medal of Honor and Call of Duty series, wrote about this on Gamasutra:

"I kept getting feedback that our shotgun was underpowered…people really kind of hated the shotgun. When I looked at the balance numbers, the shotgun was actually a little overpowered if anything. So…after much consternation I decided to attack the balance issue from the side of perception rather than through the actual numbers themselves. I went to our audio director to talk about changing the sound. He added a bit more low end to the fire sound, pulled out some midrange and bumped up the high end to give it a sharper punch. I did not tell the team that the only thing I changed was the sound, I just asked them to give it another try to see if the changes I made addressed the balance issues they were seeing. The feedback came back unanimously positive."

Animation, sound, weight. Those are some of the ingredients of a great shotgun. So how did id make the first FPS shotgun, with no history to draw on, back in 1993? 

History lesson: the original boomstick

Our love affair with the shotgun started with Doom, but for Romero, it started with two other sources: Rednecks, and Evil Dead. In one of id's earliest games, a 2D sidescroller called Dangerous Dave in the Haunted Mansion, you blast ghouls with a shotgun (and can even shoot at diagonals!). In Dave's first game, you had a pistol, but changing that to a shotgun in the sequel was an obvious move. "You're a redneck in Louisiana, of course you'd have a shotgun," Romero laughed. "We mentioned it when we were talking about Doom, we're like 'Hell yeah man, we had a shotgun in Dave and it was awesome. Why not?'"

Doom's shotgun wasn't originally in the plans for the game at all. The small team at id had the pistol, and plans for a rocket launcher, but they needed something in between. So they designed a rifle with a bayonet. The only problem: it wasn't cool enough. "We didn't like the fact that when you jabbed, it just didn't look good. It looked lame," Romero said. "We'd already had lameness issues with Catacomb 3D earlier, when you're using your hand to throw fireballs and stuff. That didn't look or feel cool. With Doom, we did have the bayonet in there, and I believe we even had it working, and it was just like, you know what? No amount of frames will make this look good."

As they started brainstorming sci-fi weapons like the BFG, their thoughts turned to Evil Dead 2. And voila: a shotgun and a chainsaw appeared. "We basically went, 'a shotgun would totally blow away that stupid rifle.' We made the shotgun, we made the chainsaw. It totally felt right in the game. We put it in, and it was just perfect. The gun cocking animation, the sound, it was perfect. The shotgun blast was great and did a good amount of damage. So that's what happened."

The Doom faithful may know that the shotgun was a Tootsietoy Dakota cap gun model bought at Toys R Us and scanned into the game using a video camera, then edited and animated in a Carmack piece of software called Fuzzy Pumper Palette Shop. It was named after a Play Doh toy. What's surprising about Romero's story is how little tuning it took to get Doom's shotgun just right. They added a spread and randomness to the firing, but treated the shotgun pellets as if they were bullets, making the gun easy to implement. And because they "wanted every gun to be effective at super far distances," handicapping the shotgun's range wasn't an issue.

"It was important that whenever we added any gun to the game, it never nullified a previous weapon. There had to be a reason for keeping the pistol around and everything else," Romero said. "The shotgun, I believe used the pistol randomness, and also added some to the spread, but not too much. So you could kill stuff at a distance. It was not like a sawed-off shotgun that would have a massive spread."

That would come later, of course, with Doom 2's double barrel super shotgun. First person shooters have since skewed towards treating shotguns more like the sawed off: close combat killers with a very particular purpose, a more compartmentalized approach to "balance" that gives every weapon its role.

"I feel shotguns live and die by where they sit in the balance," said Pearson. "It's easy to make a shotgun too effective or nerf it so it's not dominant in the weapon selection. I feel like shotguns need drawbacks, but part of the satisfaction is the exaggerated quality of wrecking opponents at close range. I prefer tight spread with damage dampening at distance. Everyone has different preferences so it depends on the game."

We can still delight in a good kill with a well-balanced modern military tactical 12-gauge, but our favorite shotguns are the ones that defy those restrictions. Look at the shotgun in Halo: Combat Evolved, which was overshadowed by the pistol but still had tremendous range and a vast ammo reserve.

Other shotguns do something unique to stand out, either in how they affect enemies and the world, or in how they let lead fly. 

Blaster master

When I get a headshot with a pistol I expect, at best, a backflip or an exploding skull. But much of the joy of a shotgun comes from its physicality. I want my enemies blown backwards by raw force. This is where other elements of the game come into play to make the shotgun itself better. A perfect example, Gaynor explained, is Bioshock's shotty:

"It reinforces what makes a great shotgun on its own—an awesome muzzle flash, great pump action animation, amazing sound design, and high destructive power—but also how important its effect on enemies can be. Not just the blood effects or how much damage it does, but how they flip, spin, and pirouette through the environment when blasted. BioShock used tech that allowed the enemies to do a crafted death animation—ie spinning through the air in response to catching a handful of buckshot in the side—and transition that smoothly into a dynamic ragdoll that leaves them convincingly sprawled on the environment in the aftermath. Blasting Splicers with the shotgun was great because the shotgun was great, yes, but also because the Splicers were such wonderful fodder, their reaction to your blasting being an integral part of the whole exchange."

This is one area where Valve's typically soft weapons really shine: Left4Dead 2's shotguns can lift a group of zombies off their feet and send them flying. They also absolutely shred enemies. Valve's Alex Vlachos gave a great talk about Left 4 Dead 2's wounds at the 2010 Game Developer's Conference, and you can see how the system works in this presentation. This applies to all weapons, but shotguns are your best bet for blowing off limbs or big chunks of torso.

Gaynor similarly praised the F.E.A.R shotgun's "effect on a highly dynamic gameworld, where firing this thing off causes dust, concrete chunks, and broken glass to fly everywhere. But of course it would be nothing if not for F.E.A.R.'s slow-mo bullet time mechanic, allowing you to enjoy the shotgun's effects at half speed, every frame of its destructive power lovingly rendered for the player's satisfaction. Jumping over a barricade, going into slow-mo, and hearing an enemy soldier shout "OOoooohhhhhh shiiiiiiittttttt" as you pull the trigger, causing him to backflip over a railing with balletic grace, is maybe one of the most satisfying interactions in any FPS game. Oh, and if you play your cards right and get up into point-blank range, this thing can straight-up mist an enemy in one shot. That's how badass it is."

Romero and Bill Munk both called out Soldier of Fortune's shotgun for similar destructive power. "Soldier of Fortune, especially for the time, really showed the brutality of a shotgun and made the player feel extremely powerful based on the gore system," Munk said. "But for overall feel I'd have to give it to F.E.A.R. The first time you experience a shotgun in slow-mo seeing every pellet fly and the ragdoll react to it is a thing of beauty!"

Soldier of Fortune sure wins for nastiness, though.

Gettin' weird with it

God I love the flak cannon. In my imagination, the flak cannon is what would happen if the god of death metal looked at a normal shotgun and turned it into an industrial tool that could conveniently be used to shred men into paste. It's not simply firing a shell when you pull the trigger: a metal piston slams forward to propel a disc the size of a hockey puck out of the muzzle, where it separates into a spreading pattern of glowing superheated scrap. You can watch every piece make bloody contact with your enemy, but it also has a utility unlike any other shotgun: bouncing those metal meteors around corners to shred bad dudes from afar. Is there any wonder it's our favorite gun ever?

When Doom gave us a shotgun to blast demons, it was novel. Now that every shooter has its own take on the shotgun—and it's usually pretty straightforward—we love the flak cannon and other alternative shotguns for stepping out of that mold.

The flak cannon's secondary fire is a perfect example: it concentrates the heavy damage of the shotgun into a single arcing grenade that's harder to land, but offers concentrated damage you won't get at range with a spreading flak cloud. Romero himself designed a shotgun that was meant to diverge from the straightforward utility of Doom's shotgun: Daikatana's Shotcycler-6.

Daikatana had rocket jumping, but because its rocket launcher fired two shots, it would really hurt. "I thought, can I make a safer rocket jump type weapon?" Romero remembered. "With the Shotcycler-6 I can do six shots, and if you jump it'll take you up to another place. I thought that would be kinda cool for people who are good, and know the secret of the shotgun jump. So it's basically six shots, who doesn't love that, with kickback enough that you can actually get propelled up in the air, almost like a rocket launcher."

Gears of War 4's Overkill is a madman's fusion of double-barrel and auto shotty: it fires a shell from one of four barrels on mouse click and on mouse release, giving you the flexibility for tactical timing or a panicked barrage of eight shots in the span of a second.

Bulletstorm's ridiculous four barreled shotgun has a charge shot that simply vaporizes enemies, burning them away to nothing but bones. It's a fitting middle finger to the concept of balance. 

And though it was a short-lived glitch, not an intentional design, I have to sing the praises of the most overpowered shotgun of all time: Battlefield 3's briefly broken underslung M26 DART. A patch made every 12 gauge flechette pellet deal the full damage of the assault rifle's primary bullets, making the spread an ungodly cloud of death. And yet it's so politely soft-spoken.

In conclusion

 Videogame shotguns are rad. When you use a good one, appreciate it: marvel at its kick, its cocking action, its thundercrack, and the knockback like no other.

"There's something inherently satisfying about video game guns that are built to be 'one shot, one kill' like, say, a hefty magnum revolver, or a bolt-action sniper rifle," said Gaynor. "And that's also the shotgun's job... with the added benefit of not really having to aim. Who could ask for more?"

Long live the gib.

Erik Wolpaw, a long-time Valve writer who has worked on game series including Half-Life 2, Left 4 Dead, and Portal, revealed today that he is no longer with the company. Marc Laidlaw, himself a former Valve writer, let the news slip on Twitter, while Wolpaw confirmed it in a status update on his Facebook page. 

Wolpaw joined Valve in 2004, and has credits on Half-Life: Episode One and Two, Left 4 Dead, Portal, and Portal 2. Prior to that, he was with Double-Fine, where he co-wrote the outstanding platform-adventure Psychonauts, and before that he was one-half of the brilliant (and sadly defunct) gaming site Old Man Murray. He's currently involved in the development of Psychonauts 2, which was successfully crowdfunded in early 2016.

A reason for Wolpaw's departure wasn't given, but it does appear to be legitimate this time around. A report that he had left Valve also surfaced last summer, but in that case it turned out that he'd just called in sick for the day. 

I've emailed Valve for more information, and will update if and when I received a reply. 

Update: The report originally stated that writer Jay Pinkterton had also left the company, but apparently not.

People celebrate Halloween in different ways. Some dress up as their favourite character, some turn their houses into haunted dwellings, and some light firecrackers and scare my dog. For modder Yogensia, however, Halloween is a time to celebrate by creating iconic horror movie weapons for use in Left 4 Dead 2.

Since starting four years ago, the talented creator has made more than 40 weapon mods for Left 4 Dead 2, which include a candy cane shotgun, Harley Quinn's Suicide Squad bat, and a Rickenbacker 4001 bass guitar. This Halloween, he modeled and textured the The Shining's iconic axe and the machete of Friday the 13th's Jasoon Voorhees, which was a collaboration between him, Rafael De Jongh, Maksymilian Genewicz, and Renato Carvalho. Yogensia told me that while he's done with the Halloween-specific creations for this year, he still has a few projects in the works.

"I still enjoy the idea of adding new [mods]," he said. "It's all about finding something that piques my interest and matches my skills, then finding free time to work on it.

"I'll most likely work on Negan's baseball bat 'Lucille' from The Walking Dead in the next few weeks."

The work Yogensia puts into each mod can take anywhere between a few hours to several weeks depending on how ambitious the project is. He tells me that the "workflow is not set in stone," and that every modder has a different way of doing things. His method starts with him modelling a high-polygon version of the featured weapon, making sure to focus on as much detail as possible.

"After that, I simplify the model to make it low-poly and usable in games, making sure the general shape still looks relatively good," he continued. "Then I do a process called 'Baking,' which transfers the details of the high-poly model to the low-poly one as textures.

"This makes the low-poly look almost as good as the high-poly from a normal viewing distance. Then I start texturing the low-poly model, and finally I convert the model to the game's format, make sure it works properly, and upload it."

Before actually modelling and creating the weapons, Yogensia says he spends a lot of time doing research and looking at pictures for reference. He tends to stick to shots from the movie itself since "Google searches tend to show a lot of cosplay props or replicas with missing details and inaccuracies."

"Axes and machetes are relatively simple, but sometimes you just want to be sure you aren't missing any small details," he explained.

Of all the iconic weapons created by masters of design and armory, Yogensia singled out the M41A Pulse Rifle from Aliens as his white whale. He's worked on a model of it for the last couple of years, taking his time and care to make sure it's as accurate as possible.

"Sci-fi rifles are, of course, more complicated than melee weapons, and if I ever release an Aliens-related mod, I'd like it to be up to the standards of the first two movies," he said.

You can check out Yogensia's work on his website and the Steam Workshop.

Seven years later, you can still rely that a popular game will find its way into Left 4 Dead 2. You can mod Fallout s 10mm pistol, scoped rifle, or holy frag grenade into the zombie shooter, among other gear. There are two separate, equally elaborate GoldenEye campaigns. There are 132 Undertale mods. You can even swap L4D2 s credits music with a No Man s Sky song.

Overwatch is no exception, and four months after launch, 51 Overwatch asset rips and mods have made their way onto the Steam Workshop, from D.Va s pistol to Torbj rn s hammer. I downloaded as many as I could and dove in.

The mods didn t necessarily have a transformative effect on my Left 4 Dead experience, but they do inject little moments of novelty. Each time you equip Soldier 76 s Heavy Pulse Rifle (M16), he does a salute gesture toward his visor and a portion of his ult sound effect plays. Ana s Biotic Rifle is a neat swap for the hunting rifle that makes it sound like a toy air gun.

The mods don t gel perfectly together: when I equipped Genji s katana, it created an issue with the Reaper model I was using in place of Coach, blocking part of the screen. The flashlight mod I used was comically bad, casting a barely-transparent projection of Widowmaker s face into the map.

What would really tie these mods together is if someone took a page from this TF2 mod and imported one of Overwatch s maps into Left 4 Dead 2 Route 66 seems like it could work pretty well, if some obstacles were added.

Check out the various Overwatch mods for Left 4 Dead 2 on the Steam Workshop.

I don't remember which game we were playing, but it was the kind of Japanese RPG that listed everything you needed to know about its characters down the side of the screen. Magic points, coins, food, all summed up with helpful numbers. Only one of them was abbreviated: HP.

“What does HP stand for in this game?” I asked my friend, an expert on JRPGs.

“Health pineapples,” he confidently replied. “You have to knock all the pineapples off before you can hurt someone.”

HP, whether it stands for hit points, health power, or indeed health pineapples, is one of many mechanics to come to video games via the original tabletop roleplaying game Dungeons & Dragons. However, the idea of representing the amount of punishment a character can take with a discrete number of points is much older than D&D. And while we might all know what the abbreviation means, it turns out that what hit points are meant to represent isn't quite so obvious.

In a 2004 interview with GameSpy, D&D's co-creator Dave Arneson explained that the earliest version of the game didn't have hit points. The rules had evolved from wargames he and fellow D&D inventor Gary Gygax played, in which a single successful attack was all it took for a soldier to die.

That changed when they started experimenting with having players control individual heroes rather than entire armies, as players identified with them much more strongly. As Arneson put it, They didn't care if they could kill a monster in one blow, but they didn't want the monster to kill them in one blow.

Arneson had previously made his own rules for a naval wargame set during the Civil War called Ironclads, and together with Gygax had collaborated on a Napoleonic naval game called Don't Give Up The Ship! Both games had a mechanic that allowed for ships to take multiple hits before being sunk, which they'd borrowed from the wargaming rules designed by author Fletcher Pratt in the 1930s. They borrowed those rules again for D&D.

In his book about the history of simulation games Playing At The World, Jon Peterson explains why hit points were such an important idea: Hit points introduce uncertainty and variance [ ] In Dungeons & Dragons, even when the prospects of a hit are near certain, the damage dice provide another potential survival mechanism via endurance, another way of forestalling death and increasing the drama of combat.

From table to screen

Like D&D, video game combat discovered a new sense of drama with hit points. Early arcade games like 1978 s Space Invaders typically killed players with a single successful enemy contact, using multiple lives to prolong the experience. Replacing that with the ability to survive a set number of hits before dying added a finer-grained rise in tension. It removes the frustration of being reset to the start of a level every time a player is so much as brushed by an enemy, and as the number of hit points remaining falls your anxiety rises in direct correlation.

Being on your last life may make you cautious, but there's a smoother transition with hit points. You gradually shift between playing more carefully as you approach half-health, biting your metaphorical nails as it dwindles below that, and sinking into erratic risk-taking when only a sliver of life remains.

Video games inspired by D&D were the first to copy hit points, as far back as 1975 games PEDIT5 and DND, which were coded for the PLATO system designed by the University of Illinois. DND was also the first game to have bosses, who could have hundreds or even thousands of what it called Hits.

The first official adaptations of D&D to PC were the Gold Box series begun by SSI with 1988 s Pool of Radiance. They followed the rules of what was then called Advanced Dungeons & Dragons closely, which meant beginning characters had very few hit points. Playing around a table there s always the option to fudge dice rolls to prevent deaths from feeling too arbitrary, but the computer was never so forgiving and players got used to reloading frequently.

Games that weren t licenced had no such problem. The first Ultima began players with a tidy 150 hit points, and the second with 400. Important non-player characters like Lord British had totals so high that killing him became seen as a challenge, and by Ultima III players were luring Lord British to the beach so they could attack him with cannon-fire, as if he was one of the naval ships in the wargames hit points came from.

Arcade games tended not to represent hit points numerically, however. Memorably, in the platformer Ghosts 'N Goblins (ported to the Commodore 64 in 1986) Sir Arthur lost his armor on taking damage, continuing to fight in his underwear.

One of the first game to represent hit points with the now familiar life bar was Dragon Buster, a 1985 dungeon crawler by Namco with a Vitality meter that changed from blue to red as you took damage from its bats, snakes, and cave sharks. While red life bars would go on to become standard, other ways of visualizing hit points have been tried with varying degrees of success.

1983 ZX Spectrum/BBC Micro game Atic Atac had a slowly depleting roast chicken that tracked your starvation, and dinosaur fighter Primal Rage used veins leading to a heart that exploded at the moment of defeat.

Other games have tried to make their life bar a part of the game world, as in first-person Jurassic Park game Trespasser where it's a heart tattoo on the protagonist's breast you have to look down at to check. In sci-fi horror game Dead Space the life bar is represented by lights on the back of your armor, which would be very useful if you had a doctor standing directly behind you. Each of these visualizations is just a way of integrating a hit-point counter into the world, but in doing so they free the player from having to correlate a number with something that should feel real and immediate. They re all still the same old hit points, under the surface.

MIDI Maze, a 1987 first-person shooter on the Atari ST, was an early example of both the deathmatch shooter and the idea of representing hit points visually. Each player was a floating smiley face, like a three-dimensional Pac-Man, and an icon of that face at the top of the screen became sadder as they took damage. Later shooters like Wolfenstein 3D and Doom would copy this idea, their protagonists' faces growing more bruised and bloody as they absorbed bullet after bullet.

On the next page: hit points through the 90s and 2000s with regenerating health and more twists from their D&D origins.

The regeneration generation

MIDI Maze is an early example of another change in the way hit points worked, as it also had regenerating health. It wasn't the first, however. The action-RPG Hydlide, released on Japanese home computers like the PC-88 in 1984, gave players back hit points when they stood still. Where other games had food and first-aid kits that functioned as magically as the healing potions in fantasy RPGs, regenerating health though no more realistic at least took health items out of the game world. It made healing an abstraction like hit points are, rather than requiring players assume Johnny Medkit has wandered the world ahead of them scattering healing items like seeds.

It was Halo: Combat Evolved that popularized regenerating health, which is ironic because it didn't really have it. Halo's hero Master Chief wears an energy shield that regenerates after a short interval without taking damage, but once that's gone he has a traditional life bar that can only be refilled with medkits.

However, the recharging energy shield was what gave Halo its famous 30 seconds of fun that happened over and over and over and over again as designer Jaime Griesemer put it, letting players pop out of cover to shoot aliens and then duck back to recharge and reload, and that's what had a lasting impact.

The idea was copied and modified by plenty of other games. Call Of Duty has become the flag-bearer for regenerating health, taking the blame for its propagation though it wasn't introduced until the second game in the series. Even in the mid-2000s as it was first becoming widespread, regenerating health was criticized by old-school shooter fans for removing some of the drama and tension that hit points represent. It's still enraging comment sections today.

Three games released in 2005 and 2006 all tinkered with ways of making regenerating health retain the sense of rising tension that hit points were first introduced to create. Condemned: Criminal Origins, Prey, and F.E.A.R. all set a floor on automatic healing so that if you take enough damage to fall below around 25% of your hit points you can't regenerate back above that line. It models a difference between taking a serious wound and the kind of graze action heroes can just walk off, and adds grit to more serious games.

When the Just Cause games toy with this, only letting you regenerate a percentage of the most recent damage you take, it can seem at odds with their over-the-top action.

Horror games have also tweaked the way they use hit points to suit the genre. Zombie game Left 4 Dead slows you down the more you're hurt, making it harder to run away from the infected as if you're a movie character being worn down by the chase. In Silent Hill 4: The Room you regain health in your apartment, but when that safe space becomes tainted it stops healing you, a mechanical sign of its corruption that ensures you feel the same dread the character would.

Back to the source

Still, across all of these games, what hit points represent isn't entirely clear. Are they purely the injuries you endure, as the suffering face of Doomguy suggests? If that's true why is it so easy to get hit points back, whether through healing items or regeneration or drinking Fallout's irradiated toilet water?

In The Lord of the Rings Online hit points are replaced by morale, which explains why singing a jaunty tune helps top it up. In the Assassin's Creed games it's synchronization, a representation of how accurately your digital simulation is recreating historical events although that raises the question of why being hurt during events where your historical analogue was also hurt doesn't improve synchronization.

Even in D&D it's unclear what hit points really are. In the Dungeon Master's Guide for Advanced Dungeons & Dragons 1st Edition, Gary Gygax wrote that hit points reflect both the actual physical ability of the character to withstand damage as indicated by constitution bonuses and a commensurate increase in such areas as skill in combat and similar life-or-death situations, the sixth sense which warns the individual of some otherwise unforeseen events, sheer luck, and the fantastic provisions of magical protections and/or divine protection.

(Charmingly, the rules then went on to explain that Rasputin would have been able to survive for so long because he had more than 14 hit points. )

Constitution, skill, sixth sense, luck, magic, and divine protection are a lot of things to bundle into one number, and raise further questions about why, for instance, poisoned attacks cause extra damage to your “sixth sense”. When asked about what hit points really are at conventions Gygax was dismissive, giving different answers to the question each time. Sometimes he said hit points represent the way swashbuckling movie heroes survive so many fights, or that they were an entirely meaningless number that represented nothing more than a way of making the game's combat more enjoyable for players. 

That second answer is perhaps the best explanation. Given that hit points started out as a way of simulating the ability of a ship's hull to weather cannon-fire, it's only natural that there's going to be some vagueness and necessary abstraction when we apply that same concept to our video game heroes. They may as well be health pineapples, after all.

On behalf of our team here at PC Gamer, I'd like to thank modders for their tireless, passionate work this year. The community of hobbyists, mapmakers, modelers, and countless tinkerers we benefit from on PC have created great things throughout 2016. I invite them to take a break: we've found the only mod we need for the immediate future.

Molkifier, who has previously turned actual cannibal Shia LaBeouf into a Hunter, has repurposed another millennial celebrity's work in Left 4 Dead 2. The Jaden Smith Tweets mod replaces the wall scrawlings found in each of Left 4 Dead's safe rooms with some choice Jaden Smithisms, whose tweets often sound like they're the collaboration of a conspiracy theorist, a spoiled teenager, and a first-year philosophy major.

That prose, as it turns out, works so perfectly in the medium of Left 4 Dead's walls that it's practically canonical.

Some of the tweets, all of which are copied verbatim from Smith's account, genuinely sound like the scrawlings of a desperate person in the post-apocalypse, struggling to make sense of it all. "It's Okay To Cry Guys," one of the graffiti reassures. "I've Bin Drinking Distilled Water For So Long That When I Drink Normal Water It Feels Like I'm Swallowing Huge Chunks of Aluminum," another complains. The text "Who Was On The Plane" appears in Dead Air, and removed from Twitter it sounds a survivor looking for the answer to who caused the infected to spread to the airport.

Others walk the line between humor and believability. "Shia Labeouf Do Not Leave New York City Without Letting Me See You"; "I'm Slowly Realizing I Need To Make A Trip Out To Norway"; "I Don't Like To Tweet But The New Hunger Games is Literally Amazing."

Elsewhere, they're glimpses into the psyche of those who miss the world they lost. It's a uniquely successful parody: one that pokes at Smith's preachy aphorisms while remaining completely at home in the context of a zombie survival shooter.
