The original Quake was a muddy medieval world of knights, Lovecraftian horrors, and grim castles. But the sequel, cleverly titled Quake II, goes in a different direction entirely. You re a space marine, naturally, who has crash-landed on an alien world called Stroggos. In a desperate attempt to prevent an invasion, Earth sent an army to the distant planet, but the Strogg knew you were coming and your arrival was a slaughter. The dropships were shot down by anti-air defences and pretty much everyone died, except you. And so, in true id Software FPS style, it becomes a solo mission.

There s a chance you don t remember any of that. After all, Quake II is not a game renowned for its deep, complex sci-fi storyline. But the inclusion of a plot, and mission objectives, was pretty unique for an FPS in the late 90s. As you play, a robotic voice regularly drones computer updated and gives you mission objectives. By modern standards that s completely unexciting, but back then it set Quake II apart from id s other shooters. It was more cinematic, and your actions felt somehow more meaningful. And by your actions I mean shooting , because that s the beating heart of the game. Shooting things, and avoiding being shot.

At the time, Quake II was a technical marvel. Powered by the id Tech 2 engine, it boasted features that seem unremarkable now, but were amazing in their day. Hardware-accelerated graphics, coloured lighting, skyboxes, and the ability to return to previously completed levels were among its once groundbreaking features. After the release of Quake II, the engine powered several other games, including, in the early stages of its development, Half-Life. Quake II also had massively improved networking, making it one of the best early examples of an online FPS. Mod support also dramatically extended its lifespan for anyone lucky enough to have an internet connection with which to download the things.

People are still making mods today, in fact, including a few that let you play the game at high resolutions and with some graphical improvements. It ll still look like a game from 1997, but it makes it a bit more tolerable to modern eyes. Character movement is mapped to the arrow keys by default, but after some rebinding you can have it playing like a modern FPS. Although, weirdly, strafing is faster than moving forward and backwards. A strange sensation that took me a while to get used to. But for such an old game, Quake II is surprisingly playable.

A big part of this is its arsenal. It s still one of the finest collections of FPS guns on PC, and every weapon you wield has a distinct personality. The chaingun rattles at incredible speeds, getting steadily faster the longer you fire it. The super shotgun is like a handheld anti-aircraft gun, and you can almost feel the power as you unload it into an enemy and hear that echoing boom. The exaggerated kickback on the machine gun, which rises slowly as you fire, gives it a sense of physicality. And I love it when you fire the grenade launcher and hear the metal clink of the grenades as they bounce around the level. Every weapon, except maybe the blaster, is a joy to fire.

But the best of the lot is the railgun. This metal tube of death fires depleted uranium slugs at extremely high velocities, which leave a blue corkscrew of smoke in their wake. The railgun is incredibly accurate it s like a sniper rifle without a scope and it can cut through several Strogg at a time. In fights with multiple enemies, a useful strategy is running around until a few of them are lined up, then firing a slug. Seeing it tear through a line of bad guys is one of the greatest pleasures in first-person shooting.

And the things you shoot are just as well-designed. Quake II has the standard FPS structure of starting you out against small groups of easily-killed grunts, increasing the challenge the deeper into the game you get. In the first few levels you re fighting shotgun-toting Guards, beefy Enforcers with chainguns, and Berserkers who lunge at you with big metal spikes and later fire rockets at you. The way enemies explode into chunks of bloody meat, or gibs to use the parlance of the times, is still gruesomely satisfying. And there are other grisly touches, like when you don t quite kill an enemy and they squeeze off a few extra shots before they finally collapse and die.

But this is just to ease you in, and it s not long before id starts throwing its meanest creations at you in force. The Strogg are weird cyborg hybrids, with mechanical limbs and eerily human, grimacing faces. Gladiators stomp around on metal legs, firing their own version of the railgun at you. Mutants are angry, feral beasts who pounce on you, usually from dark corners. Brains, perhaps the weirdest enemy, attack you with tentacles and blood-stained hooked hands. There s a huge variety of things to kill, all with unique behaviours and weapons, which keeps the game interesting especially when you re facing several types at once.

The hardest thing to stomach when revisiting Quake II is how brown it is. The switch from dark fantasy to sci-fi leaves the levels brutal, industrial, and metallic. There isn t much variety or detail in the environments, and the colour palette is depressingly muted. The actual design of the levels is great, with plenty of secret areas and multi-level arenas to fight in, but the lack of colour and almost nonexistent world-building make it feel like a bit of a slog at times. But I remember thinking this back in 1997, and really it s a game about combat, not drawing you into its world. And since the Strogg live only for war, I guess it makes sense that their planet would be like one giant factory.

When you ve fought your way through the Strogg and infiltrated the headquarters of their leader a space station in an asteroid belt above the planet it s time to complete your final objective: kill it. The Strogg leader is called The Makron, and it s a two-stage boss fight. Its first form is a powerful exoskeleton which comes equipped with a BFG10K, the most powerful weapon in the game. And, unlike your own BFG, it can fire it multiple times in quick succession. When you destroy the mech, it s time to kill The Makron itself, which also has a BFG as well as a blaster and a railgun. Luckily the arena is littered with power-ups, health, and ammo, including a secret underground chamber that can be accessed by pressing a hidden switch. When the boss falls, you step into an escape pod, and that s it. The End unceremoniously flashes up on the screen, and your only choice is to go back to the menu. Imagine if a game ended like that today.

Quake II is still a great game, and I m surprised by how well it holds up. There s something about the feel of the weapons, the way they re animated and how they sound, that makes them some of the best examples in the genre. Even the new Doom, which is a fantastic ode to this era of shooter design, doesn t have anything quite as enjoyably punchy as Quake s railgun.

WASD feels inevitable today. Once mouselook became standard in 3D games, it made little sense (at least for right-handed players) to hold your left arm across your chest to reach the arrow keys. The WASD keys were more comfortable, and offered easy access to Shift and Space. But even though WASD seems like the obvious choice now, far fewer players used it 20 years ago.

Our favorite four letter word was never a foregone conclusion, and didn't become standard through some gaseous enlightening that spread to every PC gamer simultaneously. The new movement scheme took several years to catch on, and while we can t know whose fingers found their way to WASD first, we do have a good idea of who popularized the style: the greatest Quake player in the universe, Dennis Thresh Fong.

Fong made history when he took home John Carmack's Ferrari 328 after winning the first-ever nationwide Quake tournament in 1997. And when he won that tournament, defeating Tom "Entropy" Kimzey on Castle of the Damned, his right hand was on a mouse, and his left hand was perched over the four keys we now consider synonymous with PC gaming. But even then, not everyone played that way.

In the early days of first-person shooters, Fong says the keymappings were all over the place, and even the great Thresh had only just started to play with a mouse at all. Imagine him just a few years before, sometime around 1993, as a teenager losing a match of Doom against his brother Lyle. Like many Doom players, Fong used only the keyboard. Without the need to look up or down, it was a natural choice so much that using a mouse was even considered weird. His brother, however, was playing with a keyboard and trackball, and he was winning. It wasn t every game both were excellent players but Lyle won enough that one summer Fong decided he had to learn to play with a mouse. After that, he was unbeatable.

Right after I made that switch, my skill improved exponentially, says Fong. Pretty much, from then on, I never lost.

It took some experimentation including a strange attempt to move with WADX but Fong settled on WASD and has been using it since Doom. Did he invent the scheme? No, probably not. Others were also gravitating to the left side of the keyboard for Doom at the same time. But without Fong's influence, the default could have ended up different. It might have been EDSF, or stranger configurations like ZXC to strafe and move backwards, and the right mouse button to move forwards. Some early shooters bound movement to the arrow keys. In 1994, System Shock used ASDX, while Descent used AZ for forward/reverse and QE for banking (if you didn't happen to have a joystick).

Fong tells us he even knew a player who used ZXCV to move.

I m certainly not going to take credit for the creation of [WASD], says Fong. I stumbled across it. I m sure other people started using it as well just based on what was comfortable for them. I definitely think I helped popularize it with a certain set of gamers, particularly the ones that played first person shooters."

It s likely that he did. The very concept of a professional gamer was new at the time, and Fong was well-known on the west coast as the best player around. As Fong s celebrity grew, the one question everyone asked him was: What s your config? His answer could be most readily found in Thresh s Quake Bible, which describes the WASD formation as an inverted T. And his guide carried weight. Even before his success as a Quake player, Fong was a Doom champion, and so people imitated him, just as the kids at the basketball court by my house spend far too much time trying to hit Steph Curry s 30-foot shots.

The evidence can be found on old bulletin board systems. In one thread from 1997, a poster recommends using Q and E to strafe and A and D to turn. Another suggests using the keypad for movement, and someone else says they use A, Shift, Z, X. It wasn't the case that everyone simply gravitated to the 'obvious' choice of WASD or ESDF, and in another thread, we see how Thresh's performance in the Quake tournament spread his style. His play was so impressive, the poster looking for his config speculates that it was impossible for him to turn so fast with a mouse.

Another legend, Quake programmer John Carmack, took note. Even when I was hanging out with Carmack, wherever, at E3, random people would come up and he would hear them asking me what my configuration was, says Fong. So he ended up building a Thresh stock config into Quake 2.

It was a relief. Not only could Fong sit down at any computer with Quake 2 and instantly load his configuration, every time he got the question, all he had to say was type exec thresh.cfg.

Convenient as it was, Fong doesn t think the inclusion of his config was the main factor in the rise of WASD, and I d agree. By the time Quake 2 was out, WASD was starting to feel like common knowledge. I used it, and I don t remember hearing Thresh s name associated with it at the time, though it s possible his configuration entered my consciousness two or three people removed.

And yet games, strangely, took a while to catch up. Carmack may have bundled Thresh s config with Quake 2, but when it released in 1997 the default controls were still arrow keys. A year later, though, that changed. If Thresh's Quake tournament win was WASD's first watershed moment, the second came in 1998 with the release of Half-Life. The Quake and Doom players at Valve perhaps influenced directly or indirectly by Carmack, Thresh, and other top Doom and Quake players included WASD in Half-Life s default keyboard and mouse config, which helped solidify it as the first-person shooter standard.

Valve engineer Yahn Bernier checked Half-Life's original config file for us and confirmed it included WASD. "I remember finalizing this file (maybe with Steve Bond) during the lead up to shipping HL1 but don t recall specifics about when WASD was settled on or really why. We probably carried it forward from Quake1 " he wrote in an email.

The same year, and less than a month after Half-Life, Starsiege Tribes also made WASD default. Quake 3 followed suit in 1999, and WASD's popularity grew even more. It was also the default binding in 2000's Daikatana, but Half-Life, Tribes, and Quake 3 probably had a bit more to do with its popularity.

There were still plenty of heretical control schemes in 1999 like System Shock 2's, which defaulted to WADX (and S for crouch). But WASD had momentum. If it wasn t already ubiquitous by 2004, World of Warcraft defaulting to WASD codified it for millions of PC gamers. Now it s in RPGs and MOBAs and even strategy games, controlling camera movement over maps.

Interestingly, Valve boss Gabe Newell doesn t use WASD. I personally don't like WASD as it takes your hand away from your typing home keys, he wrote in an email to PC Gamer. I always rebind to ESDF. Newell's not alone there. Do a little Googling and you'll find plenty of people arguing that ESDF is the more natural configuration.

More surprisingly, another Half-Life developer, level designer Dario Casali, also rejects WASD. Instead, he prefers ASXC. It feels natural to me, where WASD feels odd, wrote Casali. But lots of people scoff at my config.

What would PC gaming be like had EDSF or ASXC been Half-Life s default? No offense intended to Newell or Casali, but I shudder to think of it. ASXC just sounds bonkers to me. Newell's fairly commonplace ESDF is more palatable, but as Thresh echoes, it feels harder to hit Shift and Control while easier to mispress one of the surrounding keys. For me, Thresh, and millions of PC gamers, it s WASD for life.

You can read more about the history of Quake in our retrospective celebrating Quake's 20th anniversary. We're also celebrating by running a Quake server through the weekend, and Thresh himself will be playing on our US-West server today, Friday, from 3:30 pm - 4:30 pm Pacific time.

Wes Fenlon also contributed to this article.

The great and mighty Quake turned 20 earlier this week, a moment in gaming history we marked (and continue to mark) by putting up our very own PC Gamer Quake servers for the week. We've also got a really good Quake retrospective I'd encourage you to dig into here. Wolfenstein: The New Order developer MachineGames is getting in on the fun too: It's created an all-new Quake episode, and released it for free.

Happy 20th to Quake @idsoftware! As a gift to the fans, we created a new episode of the game https://t.co/BTgju8tLuI pic.twitter.com/gHlxBgjcBUJune 24, 2016

Installing the episode is easy: Just extract the archive to its own subdirectory inside your Quake directory, then run the Dopa batch file. It works perfectly well with the GOG version of Quake and presumably others as well (GOG's release is the one I tried it on), and you can trust me, it's perfectly safe and won't set your PC on fire.

I haven't finished it yet, but I'm midway through the second level and so far it's really good. The level designs have been really clever so far, with lots of secrets to find, and yes, there is a hidden (but not too-hidden) teleporter to Nightmare difficulty, if that's your thing. Enjoy!

Twenty years ago, id Software released Quake. You ve probably heard of it. What s less known is that Quake was an idea that had been gestating since id s early days, back in the era when it was best known for the side-scrolling Commander Keen series. The first Keen promised that coming soon as The Fight For Justice, an epic RPG starring Quake the strongest, most dangerous person on the continent, who would explore an epic RPG world armed with a hammer in what id was already calling The finest PC game yet. Instead, it would take half a decade before Quake s adventure came out, breaking both technical limits and id Software itself.

When Quake arrived, it was a true 3D action game everything built in polygons. Until then, most games had just faked it. Wolfenstein 3D took place on entirely flat maps. Doom offered different heights, but everything was still drawn in 2D. It wasn t possible to have rooms under rooms and the like. Duke Nukem 3D and other Build engine games, particularly Shadow Warrior, used advanced cheats to fake the effect. When you jumped into water for instance, you were actually invisibly teleported into another zone elsewhere on the map. Quake was truly 3D, doing things like spiral staircases and lava pits for real, and being as twisty and turny as it liked.

There had been full 3D games of course, like Descent, or the Freescape games that powered the likes of Castle Master even as far back as the ZX Spectrum. To do this, though, they typically had to choose between simple and slow. Quake didn t. It was a technical showpiece and it moved like a greased-up ferret on a decent PC. No excuses. No compromises.

Or at least, no technical compromises. Of Quake s three great achievements, the single-player game is easily the weakest. It s not a terrible game or anything, but where Doom still stands up as a great campaign full of detail and wonderful design despite its simplicity, Quake is a largely bland and joyless experience whose memorable moments were almost entirely restricted to the first shareware episode. They were pretty cool, though. A main menu in the form of a 3D level, with each chapter s area themed around the aesthetic to follow, forcing you to jump a lava pit to select hard mode and seek out the Nightmare mode in the small level beyond. Big baddie Chthon, hurling fire in his lava lair. The first time having your face eaten off by a Fiend. The low-gravity physics of the secret level, Ziggaurat Vertigo. They re effective, as was the experience of being in a fast-paced 3D world full of action.

Players hoping for a constant stream of such innovation were disappointed. Despite the Lovecraftian influences, there was little to fear or any sense of anything great going on. There were no more giant, dramatic bosses, with the final one, Shub-Niggerauth, just being a static blob defeated with a cheap telefrag rather than a weapon. There was little sense of place. The levels were murky shooting galleries, where even Doom had tried to make its locations feel like real locations to whatever degree of real you can get from starbases slowly being taken over by biotechnology. Certainly players just coming in from Duke Nukem 3D and its real-world settings and constant variety couldn t help but be disappointed, even if Quake has honestly aged much better. It s still dull, but at least unlike Duke it s not writing cheques its engine long stopped being able to cash, and much easier to take as a simple shooter rather than a bigger Experience.

The main problem was that after years of promises and expectation, to have a game that was basically Doom again only set in a castle was something of a letdown both internally and externally. All the RPG features, most planned new gameplay concepts, even the idea of a main character wielding a hammer, had been sucked out, mostly to get the thing out of the door. This led to a major schism within id. John Romero packed his bags to go start Ion Storm and create the more narrative/detail driven game that he wanted to make. (In a case of history repeating, his co-founder Tom Hall had done much the same over the original Doom, which he d also envisioned as being much more of a story-driven experience than the shooter it ended up being.)

Luckily, multiplayer was a whole other matter. Here, the stripped down simplicity and full 3D allowed for fantastic arena design in genuinely atmospheric levels full of cubby-holes to camp and launch assaults from, and even the occasional gimmick, like hitting a button to slide back a level s floor and drop unwary players into a pool of lava. It felt great. The weapons had real kick. Gibbing other players was a pleasure.

Outside the game, it helped that by 1996 online play was finally becoming viable for PC gamers across the world. While Doom had spawned a huge scene in its day, getting online in 1993 was a pipe dream for most players outside of universities. At home, gamers were lucky to have a null-modem cable to connect two PCs together, never mind enjoy the fun of epic LAN parties. Of course those who could got to enjoy a truly wonderful experience.

And so, people played Quake, and saw that Quake was good. The rocket jump alone took Quake to a whole new level. This wasn t an id invention, but a discovery by fans, so of course the maps hadn t been designed to handle it. The result? One of the net s first famous speed-runs Quake Done Quick, in which the whole game was obliterated in under twenty minutes with tricks like bunny-hopping to raise incredible speed, and rockets to hop through what were meant to be tantalising doors only intended to be accessed after collecting a key or going all around the houses.

Playing fairly or not, the raw sense of place and weight that 3D offered soon made the fakery of 2.5D untenable. It became impossible to ignore that sprites were just two-dimensional, and that when killed, their collapse was a totally canned animation rather than reacting properly to physics (though it wouldn t be until Half-Life that games took the next step and made it standard to give characters skeletons instead of keyframed animation, ushering in the still ongoing ragdoll comedy era).

What all of Quake s technology really empowered though was its community. It was the first game-as-platform, made possible by not just by the 3D engine, but Carmack including an interpreted language called QuakeC that allowed modders to do more than simply create their own levels and make the monsters look like Bart Simpson. They could completely bend the engine to their wishes.

And the modding community ran with this. When you bought Quake, you were buying into a whole universe of content online. Initially this was limited to simple-but-cool additions, like giving the player a grappling hook to scale and swing around levels in ways that had been impossible with previous 2D engines. Experiments gave way to full total conversions like AirQuake, which swapped the players out for vehicles and turned deathmatch into a 3D vehicle combat game. Others proved that the sky wasn t close to being the limit. A little game called Team Fortress, for example, began as a Quake mod, launching with the Scout, Sniper, Soldier, Demoman and Medic classes and building from there.

The ability to create stages, have polygonal characters, and have multiple people control them in scenes also spawned machinima filmmaking. Quake s early examples of machinima may be the Fred Ott s Sneeze of the genre by modern standards, with celebrated stuff like Blahbalicious and Apartment Huntin now looking somewhat yeah... in the era of Red vs. Blue and Source Filmmaker and whatever the hell people are doing to the Overwatch girls today. At the time though, they were often very impressive, especially when run live in-engine, and did pave the way for something new.

Much as the Doom mapping community still puts out new levels, Quake still has a modding scene. This month sees the release of Arcane Dimensions 1.5. Last month, a brand new set of gun models joined the fray. Also, Carmack open sourced Quake s code in 1999, coders have been able to completely overhaul the old engine and bring it much more in line with modern standards. Darkplaces offers real-time rendering of light and shadow, and likely Quake as you remember it looking if you haven t played it for a while, while others, like QuakeSpasm focus more on accuracy.

No game since has managed to replicate Quake s spectacular level of success as a canvas for modding. Others have impressive modding communities, for sure, but not the same scale. With Quake, anything seemed possible as long as it didn t take too many polygons. Games like Second Life tried to replicate the phenomenon online, and of course, now would-be programmers can get their hands on the likes of Source and Unity and Game Maker for free or almost free, rendering modding less important at least for making total conversions or a wholly new game out of the bones of the old.

However long it lasted, the Quake era was important kickstarting many an industry career, as well as providing the kind of playtime that most games can only dream of supplying. Some mods even got a commercial release, though not necessarily fondly remembered ones. X-Men: The Ravages of Apocalypse, anybody? The answer, in case you re wondering, is hell no .

Finally, the Quake story became weird. After two official expansions (Scourge of Armagon, aka The One Without The Dragon In It , and Dissolution of Eternity, aka The One WITH The Dragon In It ), id disappeared for a while and released Quake 2 as a single-player focused SF shooter in which you played a space marine fighting the unfortunately named Strogg. It was not very good. At all. Its main contribution to the world was, along with Unreal, teaming up with 3D accelerators to splash coloured lightning around the world whether it liked it or not. Then Quake 3 ditched all of that for a futuristic arena shooter starring characters like a giant cyborg eye before Raven s Quake 4 went back to the Strogg nonsense for another single-player focused game.

With the newly announced Quake Champions, it seems clear a new Quake game is no guarantee of a particular story or style, but rather a way for id to make use of owning the name. Despite that, close your eyes and picture Quake . What comes to mind isn t just another game to be ticked off as completed, nor a technical achievement to be respected, but that rare game that blew past its limits. Quake lives on to some extent in just about every shooter that followed it, and made gaming a better, more advanced, and endlessly more exciting place for its existence.
