The Steam Workshop is a giant thing, containing over 24,000 Skyrim mods, over 413,000 Portal 2 levels and, for some reason, over 100 Goat Simulator characters and mutators. It's also a profitable thing. Team Fortress 2, Dota 2 and Counter-Strike: Global Offensive all have curated Workshops—letting players pick the community-made items that will go on sale in the game.

Valve has now announced that, since the launch of the Workshop in 2011, the total payments to individuals for the creation of in-game items has surpassed $57 million.

Previously, only Valve games had curated item Workshops—something Valve attributes to the "sheer number of challenges required in order to scale to a global audience of creators and players". Seemingly, these hurdles have been overcome, as the Workshop is now hosting curated item Workshops for Chivalry: Medieval Warfare and Dungeon Defenders: Eternity.

"Purchases of this great new content directly enables those community members to continue practicing their craft and making more awesome content," writes Valve, before going on to say that they expect more curated Workshops in "the coming weeks and months".

Welcome to our roundup of the best total conversion mods ever. Presented in no particular order, these are the mods that radically transform our favorite games into something different, with new and improved art, gameplay systems, locations, and adventures. Crafted through years of work, sometimes by large teams of volunteer modders, many of these mods have gone on to become PC gaming classics in their own right.

Here are the best total conversion mods ever made. 

Link: Sven Co-op on Steam

First released way back in 1999, Sven Co-op is still being both updated and played today. A cooperative mod for the original Half-Life, the mod allows groups of players to battle their way through the Half-Life campaign, where they'll find increased challenges and far more enemies, as well as new maps filled with puzzles and challenges. Over the years hundreds of new levels have been added along with new weapons, improved AI, and lots of customization options. Even if you don't own Half-Life, you can play it for free on Steam.

Link: A Game of Thrones mod site

For Game of Thrones fans, this mod is already at the top of your personal list or will be the moment you try it. It transforms CK II’s medieval Europe into the beautifully realised continents of Westeros and Essos and populates them with characters and events straight from the source material. Marry, mingle, or murder your way through the Starks, Lannisters and many other notable dynasties. Best of all, random game events will quickly spin the world into an enjoyable alt-reality of the fiction we’re so familiar with. This is an absolute must-have for gamers who are fans of the George RR Martin novels and the HBO series.

Link: Aliens TC ModDB page

Way back in 1994, this pioneer of full-conversion mods successfully recreated the 1986 sci-fi action film Aliens in Doom. It didn’t settle for just plopping face-huggers and aliens on a map, either: its custom levels mirror familiar locations and story beats from the film and even provide sound effects and voice clips lifted straight from the movie. Hearing Sergeant Apone through your headset reminding you to “Check those corners... check those corners!” not to mention Ripley furiously shouting “COME ON!” when climbing into her signature loader to do battle with the alien queen genuinely made me feel like I was part of the Aliens universe.

Link: Counter-strike ModDB page

You may have heard of it? The multiplayer Half-Life mod featured such team-based missions as hostage rescue and bomb defusal, each team with its own equipment and goals. With its quick rounds and exciting gunplay, Counter-Strike became an instant hit, and the community began creating maps of its own. Counter-Strike’s emphasis on teamwork and communication helped define a new genre of shooters, and the modders behind it were quickly hired by Valve.

Link: Nehrim site

Every full-conversion mod comes with a high degree of ambition, but it’s a truly special situation when the mod’s creators have the talent to match. Nehrim: At Fate’s Edge, created by German modding team SureAI over four years, does what the best full conversion mods do: reshapes the features that are lacking in the original game and provide hours of exciting new content. With original voice work by dozens of actors, big changes to several of the game’s familiar systems, and its own quests, story, lore, playable races, and a massive and beautifully designed new map to explore, Nehrim transforms The Elder Scrolls IV: Oblivion into an entirely new experience.

Link: Garry's Mod ModDB page

Plenty of games have a god mode accessible through console commands, but Garry’s Mod takes the idea to an entirely new level. A multiplayer sandbox limited only by your creativity, the mod has proven to be the ultimate tool for creating webcomics, videos and custom game modes, as it enables players to spawn objects and entities and pose them however they like. You can even play Half- Life 2 using all of the mod’s tools, turning Gordon Freeman from a simple gun-toting scientist into the ultimate expression of your will.

Link: Long War at Nexus Mods

Harder, longer, and with hundreds of changes to the base game, Long War extends XCOM's campaign, lets you play with up to 12 squad members at a time, adds new soldier classes, voice packs, weapons and technology, and lots of improved and completely overhauled systems. Long War wasn't just a hit with players but with XCOM's developers, who brought the mod team in to work on launch-day mods for XCOM 2, as well as create Long War 2.

Link: The Dark Mod site

This mod isn’t simply a celebration of the acclaimed Thief series using Doom 3’s engine, but actually an improvement on some of its features, especially the wonderful and engaging new lockpicking system. The open-ended stealth adventure lets you slink through a gorgeous, highly-detailed gothic steampunk world as you fill your pantaloons with loot and try to avoid detection. Most importantly, the mod comes with its own mission editor, enabling members of the community to create and submit their own custom levels and stories. The Dark Mod was released as a standalone game in 2013.

Link: Black Mesa site

It sounded like an impossible project: building the entirety of the celebrated FPS Half-Life in Half-Life 2’s Source engine, but after eight years of work by a large volunteer team of modders it finally became a reality. While it stops short of recreating the entire game (Gordon Freeman’s leap into Xen is the mod’s endpoint), it’s still a remarkable accomplishment. For Half-Life veterans it contains a mix of new design elements and familiar confrontations, and it’s a also great way to experience the ground-breaking adventure for those turned off by the dated graphics of the original.

Link: DayZ mod on Steam

In a game featuring starvation, sickness, and swarms of growling zombies, it still falls to other human players to provide most of the horror. While the standalone version of DayZ became a big hit in Early Access, the original open-world multiplayer survival mod is perfectly playable. The vast map and lack of global chat provide a feeling of intense loneliness, but the prospect of actually meeting someone else is a constant threat.

Link: Complex mod site

The name is certainly apt: this mod takes the real-time space strategy game and adds an almost absurd amount of complexity to nearly every single aspect. Alongside improvements to the AI, physics and graphics, the mod adds scores of new units and maps, constructible subsystems, deeper tech and research trees, and a diplomacy system. It even adds an actual calendar so gametime can be marked in years as in the Civilization series.

Link: Dota Allstars, a recent iteration of the original mod, worked on by IceFrog, who now works for Valve on Dota 2.

An exciting combination of RTS and RPG, the multiplayer battle arena mod for Warcraft III (based on a modded map from StarCraft) is a lot of things: simple to understand, difficult to master, and most of all, utterly addictive. In its early days DotA was a project that was passed from modder to modder, and like an unending stream of creeps it eventually spread through the gaming world to become a massive hit, as well as the first lanepushing game to have sponsored tournaments.

Link: NeoTokyo site

This team-based multiplayer mod for Half-Life 2 is set in a slick, futuristic cyberpunk city and features three different classes to choose from, each with their own distinct weapons and strengths. With lethally realistic gunfire and cloaking abilities available to some classes, NeoTokyo requires more stealthy and tactical play than many online shooters demand. Inspired by anime classics Ghost in the Shell and Akira, NeoTokyo also features an amazing and engrossing custom soundtrack that you’ll want to listen to even when you’re not playing the game. The mod was released as a standalone title in 2009.

Link: Mechwarrior: Living Legends site

Combining FPS action and simulation, this large scale multiplayer-only mod brings wonderfully realised Battletech mechs to life in Cryengine 2, though it began as a mod for Quake Wars. Tanks, jets, mechs and hovercraft strategically battle for territorial control in beautiful, varied, highlydetailed outdoor environments with full day/night cycles. The mod was so impressively made it was even sanctioned by Microsoft, who own the Mechwarrior franchise the mod is based on.

Link: Cry of Fear ModDB page

While it’s a standalone release now, Cry of Fear began as a Half-Life mod. It’s the story of a man who wakes after being hit by a car to discover his city is filled with gruesome monsters and his mind packed with psychological horrors. The mod has some interesting and immersive tweaks, such as an extremely limited inventory—and the fact that the game doesn’t pause while using it—that bring new challenges as you play through a disturbing, winding story with original animated sequences and multiple endings.

Link: Genkokujo ModDB page

The Sengoku period in Japan was a time of turmoil, political intrigue and near-constant warfare. What better time and place for a massive, openworld combat RPG built on the capable framework of Mount & Blade? The mod features actual clans and figures from Japanese history, new skins and armour types, new gunpowder weapons, and dozens of historically accurate locations spread across a map of Japan with twice the playable area of the original game. It also incorporates a number of other excellent M&B mods such as Diplomacy and Freelancer, which add even more great features.

Link: The Stanley Parable on Desura

You’re put in control of a clerk who suddenly finds himself completely alone at the office, but you’ll soon start to reconsider just how much control you actually have. While difficult to describe, the mod quickly proves to be a witty and insightful commentary on videogames, particularly the act of making choices. It’s also wonderfully narrated by a voice so soothing you’d like him to read you bedtime stories – if only you could trust him. It’s now a complete game with a lot more polish and an extended story, but the original mod remains a thoughtful, oddball delight.

Link: The Third Age on TWCenter

Every kid who ever picked up JRR Tolkien’s The Lord of the Rings novels has longed to step into Middle-earth, and one of the best ways to do it is with this mod for the turn-based strategy game Total War, capable as it is of portraying epic-scale battles. Third Age features over a hundred accurate locations and a dozen factions straight from the fiction. It includes custom units such as ents, trolls, giant spiders and wargs, and lets you play not just as heroes like the men of Gondor and the Silvan Elves, but also as the evil forces of Sauron’s Mordor, Isengard, and even the orcs of the Misty Mountains.

Link: Out of Hell ModDB page

As Donovan Ling, a lone cop investigating a garbled transmission from the industrial town of Grinwood, you quickly find yourself alone and fighting to survive a relentless zombie invasion. This mod is packed with astounding visuals of a city gone to hell, and a chilling original soundtrack accompanies you as you battle your way through more than 20 harrowing and atmospheric maps. Despite an arsenal of deadly weapons and melee attacks, you’ll never really have time to catch your breath.

Link: Natural Selection site

With one team playing marines and the other playing aliens, Natural Selection converts Half-Life into a multiplayer hybrid of first-person shooting and realtime strategy. It brought to life the concept of a commander in an FPS: a sole player who views the map in top-down fashion, giving orders, issuing supply drops, and managing the map in a traditional RTS fashion. The aliens have no overlord or shared resources, so must rely on communication if they want to win. Despite big differences in the two teams’ abilities and tactics, the mod remains a tightly balanced experience.

Link: Team Fortress ModDB page

Long before it evolved into a cartoony hat-trading simulation, Team Fortress was a mod for Quake. It originally featured five classes, later blossoming into the full iconic nine we’re familiar with today, and even provided a tenth class, the civilian, playable during VIP escort missions. Instead of just red and blue teams, certain maps for TF included two additional teams, green and yellow, struggling for map control and engaging in capture the flag games. The mod’s popularity led to a proper release and, much later, the Team Fortress 2 we know today, although the original mod is still played on a few servers.

Link: The Nameless Mod site

With a hundred new skins, sixty maps, custom cinematic sequences,and two storylines providing a hefty thirty hours of playtime, The Nameless Mod grew, over seven years of development, from something of an in-joke to a true mod masterpiece and Deus Ex fan favourite. Part homage and part satire, the mod sports thousands of lines of custom dialogue, tons of tweaks, and dozens of great new music tracks, not to mention books, newspapers and emails.

Valve is pretty much an unknowable obelisk: giant, powerful and unfeelingly silent. Due to this absence of communication, the few voices that do emerge from the studio are amplified ten-fold. Hence why you may recognise the name Yanis Varoufakis. During his time as Valve's economist-in-residence, he ran a blog dedicated to analysing and explaining the studio's virtual economies.

Now, Varoufakis has a new job. He's today been named Greece's finance minister.

Varoufakis was at Valve from 2012-2013. Despite not playing games, he said in his introductory post that he was fascinated by the virtual economy Valve had built—specifically that it was an economy with hard data for every transaction. "Think of it: An economy where every action leaves a digital trail, every transaction is recorded;" he wrote at the time. "Indeed, an economy where we do not need statistics since we have all the data!"

Through Varoufakis's analysing, we learned how gifting played a part in TF2's economy, how a sophisticated bartering and arbitration formed around trades, and how Valve doesn't even fire people like a normal company.

Varoufakis's role as finance minister is quite a departure from the academic study of non-existent headwear. Greece was hard-hit by the economic crisis, leading to a debt crisis that has resulted in high unemployment and bankruptcy. Varoufakis himself is seen as a radical—one who has referred to austerity measures as "fiscal waterboarding".

That, though, is the purview of serious political reporters. As a videogame reporter, I feel it's my responsibility to do something dumb. Here, then, is a series of suggestions Varoufakis could take from his days at Valve that would instantly, definitely, fix Greece's economy.

• Randomly give a fish on a stick to citizens as they go about their day. Also, sometimes a trilby.
• If you set a hat on fire it is worth more money. Because reasons.
• All trade will now be based on the conversion rate: Two Refined = Stout Shako.
• The most valuable thing you can own is now a decapitated rabbit's head.
• Abolish physical crop exports. Switch to digital :weed: exports. They're worth more.
• The Trojan Horse, but with Crates.
• Make Half-Life 3

Aperture Science isn't the only one with a secret underground base. Deep in the Antarctic lies a hidden subterranean facility, filled with puzzles, lined with traps, and shrouded in mystery. Why is it there? What is its purpose?  Below the Ice, a mod for Half-Life 2, invites you to find out. Just watch your step.

The mod begins with you arriving in the Antarctic, where you quickly stumble upon the entrance to a facility buried in a glacier. There's a sign warning against trespassers, which feels a bit pointless. You've either traveled all the way to the north south pole and aren't going to turn around and go home because of a sign, or you're a polar bear penguin and you can't read anyway.

Entering this facility requires passing a bit of an intelligence test in a number of grid-like puzzle chambers. Many involve the simple pushing of buttons, though figuring out how to reach those buttons, and what those buttons actually do, can take a while. The chambers aren't particularly forgiving if you make a mistake, either. Prepare to be crushed, fried, or fall to your death if you slip up.

Once you've convinced the puzzle chambers you've got a brain in your head, you're granted access to the rest of the facility, which appears to have been abandoned. While exploring, you'll discover living quarters, science labs, and a series of offices. There, you'll begin to piece together the story behind the facility, which ties in to both the fiction of Half-Life 2 and Portal. It's not just a matter of walking around and reading notes: even though you've escaped the test chambers, there are still plenty of puzzles to solve to gain access to the facility's control rooms, observation chambers, and science labs.

The more you progress, the more the facility begins to reveal its secrets, and its true size. While you're navigating the place, unlocking doors, turning on lights, locating missing pieces of technology, dabbling in teleportation, and piecing together its history, also keep an eye out for a series of memory sticks. Find enough of them hidden throughout the mod and it will give you an alternate ending.

There's probably a few hours of play here, depending on your smarts. Some of the puzzles aren't particularly sophisticated: to progress, it's generally more important to carefully examine your surroundings for clues than to be some sort of 10th Level Puzzle Wizard. There's some decent music throughout, and while the map's set dressing is a bit plain, and a few custom textures are a little underwhelming, it's a nice mod if you're in the mood for some gently-paced puzzle solving.

You can grab the mod here and untangle the mystery for yourself. To install, extract the folder into your sourcemods directory (\Steam\steamapps\sourcemods), and restart Steam. Below the Ice will appear in your library. You'll also require Half-Life 2 and Source SDK Base 2013 single-player. You can find the latter by viewing your Games Library in your Steam client, selecting "Tools," and double-clicking it from the list.

The PC doesn't have a platform holder, and that's a blessing. But there's no denying that Valve's role is an important one in the industry, and that its decisions often have a tremendous impact on our hobby. With great popularity comes great responsibility: here's how we'd like to see Valve apply itself this year.

Make TF2 exciting again

Phil Savage

My favourite Valve thing of 2014 was the anticipation around the release of Love and War update. There was excitement, there was speculation, there was a funny Source Filmmaker video. It was everything a TF2 update used to be, with one exception: the update. There was a time when TF2 updates warranted the amount of excitement they received. The class events were significant. They dramatically changed the way you could play a class—giving new, divergent tactics to familiar operators. Also maps. TF2 launched with six maps. It now has over 70.

The Love and War update didn't have that game changing feeling... Sorry, I'll try that again. With the exception of the Conga taunt, the Love and War update didn't have that game changing feeling. The weapons were good, but I don't think weapons—even something as well-defined and desirable as the BASE Jumper—carry the same weight they once did. When there's only one way to play a class, a new item set has massive ramifications. Now there are multiple ways to play, and one more doesn't make as much difference.

In all, 2014 was a quiet year for TF2. Even the long-anticipated End of the Line community update was muted by Valve's decision not to include the Snowplow map. Their reason, supposedly, was that it was deemed too confusing and challenging for new players . And this is from the people who made Hydro. This is my worry with Valve now. It feels like they're afraid to take risks. The most exciting new inclusion of the year was the grappling hook, and that happened without fanfare as part of the Mann Co. Beta initiative.

Imagine if the same energy and excitement leading up to the Love and War update was rewarded by a new game mode, new maps and a goddamn grappling hook—all definitively released, rather than hiding away in beta. TF2 would, once again, feel like an event. Yes, maybe one of those maps would be terrible, but that would only make it more exciting when more maps appeared—these ones learning from past mistakes.

Aside from the Halloween event, every map added to TF2 in 2014 was released into beta. In 2015, I'd love to see the confidence come back. To see the TF2 team declare something ready—not just with a release, but with a week-long build-up that showed how a seven-year-old game could still feel fresh, exciting and essential.

Make the Steam Controller work

Tyler Wilde

It feels like ages ago that we were all talking about Steam Machines and the Steam Controller. It wasn t really that long ago, but Valve went pretty quiet on both fronts after a generating a lot of interest. I m still interested—not so much in Steam Machines, because if I stick a PC under my TV it ll probably be a laptop or something I build myself, but in the Steam Controller.

I m fascinated by what Valve s trying to do with the thing. Back when Evan tried it last year, he found the trackpads unwieldy, but if Valve can really design a new kind of controller that both emulates a mouse (and it ll never be as effective, of course) and works for games I d rather play with a d-pad or analog stick, then we may have a new best PC gaming controller in our hands. It s promising that, after we were a bit unimpressed by the first demos, new mockups keep appearing, which suggests that Valve is still tinkering with the whole design. I hope we see the latest prototype soon, and I m betting we will at this year s GDC.

Grow CS:GO

Evan Lahti

CS:GO became, with plenty of breathing room, the second-most played game on Steam in 2014, hitting 400,000 concurrent players for the first time this month. A lot of that growth is owed to CS:GO s reawoken popularity as an e-sport: more people than ever are watching competitive Counter-Strike, and the recent DreamHack Winter tournament (even with a bit of controversy) was an exciting watch.

But Valve s content updates, patches, and e-sports aid hasn t come close to the support given to its flagship game, Dota 2. CS:GO s support isn t proportional to its popularity, and Valve faces a playerbase that s hungry for anti-cheat fixes, new maps, weapon skins, and ways to engage with the game they re invested in if they want CS:GO to retain its position as the most popular FPS on PC against games like Evolve and Rainbow Six Siege.

Valve needs to continue to keep pace with hackers, and it needs to look to the old days of TF2 for ideas on launching in-game events that don t simply feel like money-grabs veiled in playfulness. But what would really propel CS:GO is a proper, The International-level major tournament—something that Valve owned and operated itself rather than relying on CS:GO s great-but-fragmented leagues to build interest around it as an e-sport.

Beyond that, I d love to see a CS:GO API opened up. Part of Counter-Strike is eliminating bad habits, and right now there s no easy way to track your match history (beyond watching your last few replays) or dig into meaningful stats.

A full year of Dota 2 updates

Chris Thursten

In 2015, I'd like to see the Dota 2 team continue to open up about their plans and processes. At the same time, I really hope that they're able to make this a bigger year for the game than last year. A lot of time has been invested in an engine update that will introduce custom game modes and make it easier for Valve to develop new additions in the future. That's great news - and user-generated content represents a potentially exponential increase in the game's scope. At the same time, I don't think I'm alone in wanting a stronger run of official updates. That means more new heroes in 2015 - potentially the first Dota 2-specific heroes - and proper seasonal events.

Valve may not see it the same way: they could argue, convincingly, that the future of Dota 2 was and should be in the hands of its community. Be that as it may, I think the last couple of years have shown that leaving everything up to the wisdom of crowds creates confused expectations and entrenches divisions. From the pro scene to the potato bracket, the Dota 2 community could use a bit of stability - and a solid year of official updates from Valve could help establish that.

Steam would benefit from a visual overhaul

Andy Kelly

Steam s feature set took a big step up with the addition of curators and, er, the colour blue in the client s basic skin in 2014. I would like to see a bit of housecleaning on the design of it—maybe contemporise the fonts a little bit. Reskinning is obviously an option, but I d like Valve s basic layout to be little more up to date. It s still very similar to when I first signed up years ago. On the one hand, that familiarity is nice, but on the other, Big Picture Mode and the Steam app on iOS show how much cleaner the basic layout of Steam could be with a refresh.

The thing we all really want

Chris Livingston

Let's address the strider in the room. For years now, every single bit of Valve news and every update Steam pushes through has resulted in a fresh round of sarcastic yet subliminally hopeful chatter: Half-Life 3 confirmed!

To which I say: slow your roll, Internet. We've got some unfinished business to attend to. A broken promise. A missing chapter. A little something called Half-Life 2: Episode 3.

I'm confident this is, deep down, what we all really want: another two-to-three hours of content using the same assets and enemies from Half-Life 2. We want to fight more slow, stupid Combine soldiers while they issue their familiar barks. We want to solve yet another giant see-saw puzzle with the gravity gun. We want to stare at a brick wall waiting for a new level to load, then run through the new level for three minutes, then stare at another wall while the next level loads. We want to climb back into that rusty, ugly-ass car and hit the gas only to immediately hit the brakes because the radar is showing a supply cache. We want to spend more time watching Alyx Vance do a bunch of cool things like bashing zombies with the butt of a shotgun or using a sniper rifle or climbing over walls, which we, as Gordon Freeman, cannot do ourselves for some reason. Most of all, we need to hold Valve accountable for their promise, made in June of 2006, that the three episode series will conclude by Christmas 2007. That's the "three" that's important, here. Not Half-Life 3. Episode 3. Make it happen.

j/k, of course. This year, Valve, just announce something, anything genuine about Half-Life 3, even if the announcement is that it's never going to come.

Valve's Source Filmmaker is regularly used to parody Team Fortress 2. Here, instead, it's being used to accurately (and stylishly) portray an entirely different game. With the help of TF2's Heavy, and taking a mere 24 seconds, here is Skyrim in a nutshell.

The short was created by Ferhod, who previously made the Saxxy 2014 winning TF2 film Animation vs. Animator.

Something is happening over at BMRF.US, a website associated with the Source-based Half-Life remake Black Mesa: Source. The site is repeating an emergency broadcast warning of "a disaster of unknown type" that has occurred at the Black Mesa Research Facility, and ordering the immediate evacuation of everyone within 75 miles. Half-Life 3 confirmed?

Well, no, I think we can safely say that's not it. But the warning may have something to do with a coming launch of Black Mesa: Source as a stand-alone game on Steam. It was originally released as a free mod in 2012, and in late 2013 was among the first games to get the Greenlight on Steam—a somewhat surprising development, given that it's based entirely on Valve's intellectual property.

It's generally assumed that when the commercial launch rolls around, it will include the Xen levels, which weren't included with the original mod. According to a post on the Black Mesa: Source forums, however, one of the developers said the alert "has nothing to do with the imminent release of Xen," but added that more hints may be in the offing.

It's worth remembering that the BMRF site was actually part of the Black Mesa: Source ARG that launched shortly after the mod was released, and as noted by Reddit, the site is owned by the Black Mesa web developer. It's legit, in other words, but legit what, exactly, remains a mystery.

As part of this year's Smissmas celebrations - it's a thing - Team Fortress 2 has received a new way to play it. It's called Mannpower Mode, and it features grappling hooks.

Merry Smissmas, one and all!

Mannpower Mode is very much a beta offering, being used to test the water for a bunch of different mechanics, including the grappling hooks. Because there are grappling hooks in it.

Currently you can play the capture the flag-alike Mannpower on modified versions of the Ctf_foundry and Ctf_gorge maps, and as well as the grappling hooks (did I mention those?) there are a few other tweaks and features added.

Nine power-ups, including strength, resistance, haste and warlock, are currently available, though there are more on the way. Each... well, powers you up, obviously, just in a different way for each of the nine.

There's also a grappling hook! Wait, I said that a couple of times already. But the fact is, grappling hooks are brilliant and should be in all games - so it's great to see them added for all classes in Mannpower Mode.

Accessing it is as simple as this: "Click on Play Multiplayer, enable Play Beta Maps checkbox, and then choose Mannpower Mode."

Grappling hooks!
