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.

Microsoft bought Mojang yesterday you may have heard something about that. You may also have heard grumblings from some corners of the community that Minecraft creator Markus "Notch" Persson "sold out" by taking the money and abandoning his game and, by extension, his millions of adoring fans to the fickle whims of of a corporate villain. But Garry Newman, the man behind indie darlings Garry's Mod and Rust, says he'd do exactly the same thing if he could, and you probably would too.

Newman pointed out in a blog post that went up shortly after the Mojang deal was was confirmed that everything changes for an indie developer once he starts hiring people to work for him, because you're suddenly responsible for a lot more people than just yourself. Citing the case of Blitz Game Studios, which shut down in September 2013, laying off 175 employees, and then effectively re-launched in November under a new name, he wrote, "Those are the guys you don't want to be."

"I am sure more than the top guys at Mojang became very financially rich due to this deal and that's something that should be admired not seen as a bad thing," he continued. "Long story short, I d have done the same thing. The money is enough to very much take care of all the staff. The game is in relatively safe hands. Mojang s legacy is as a huge success story instead of a one hit wonder. Everyone wins. Can you seriously say you d have done it differently?"

No, Garry. No, I cannot.

It could only happen on PC: Garry's Mod, a seemingly pointless sandbox allowing all manner of ridiculous and perverse experimentation, has managed to sell 6 million copies. The news comes via Garry Newman himself, who managed to drag himself away from mountains of cold hard cash for long enough to Tweet the news.

Garry's Mod originated as a Half-Life 2 mod. It hit Steam in 2006 and, according to figures from April 2013, has earned over $22 million. More than a year later, and since the game went standalone earlier this year, that figure has no doubt increased significantly. As reference, the game had sold a mere one million copies back in 2011.

Along with the new sales milestone Newman provided a platform breakdown for the title. The vast majority sold for Windows, 336,765 sold for Mac and 28,322 for Linux.

As for the future of Facepunch Studios, Rust is still in development, albeit in Early Access, while Riftlight is a newly announced topdown shooter which looks pretty sweet.

 

The ESL One Cologne 2014 CS:GO championship went down as the most-watched Counter-Strike event in history, with over 400,000 combined viewers watching live in-game or through the ESL stream over the weekend. There were plenty of memorable frags, clutches, and comebacks during the 16-team, four-day event, the best of which I ve collected here.

Source is certainly showing some wrinkles in comparison to, say, UE4, but CS:GO remains the premier competitive shooter on PC today. Even after a decade half of history with the franchise, we still love the look and feel of its classic maps and their modern iterations: Mirage's A bombsite, Inferno's "banana" path, or Dust 2's dim tunnel.

Firing up CS:GO on LPC, I decided not to go with a triple-wide monitor setup, so I arranged our three 27" monitors in portrait configuration. This gave us a combined resolution of 4320x2560 or 25 percent/3 million more pixels than we'd get at 4K.

Garry Newman trolled me. I asked the Garry's Mod and Rust creator to show us his computer setup and he told me, flat out, that he doesn't use a standard PC. Then I asked him to send pictures of the setup and he included male genitalia on one of his monitors. Dude is messing with me.

But when you're Garry Newman, looking in on the ridiculousness of the industry, you can do that. You can see the notion that a game developer should have some hand-crafted PC with a giant case and laugh. You can get an email from someone about showing off your rig and decide to have a little bit of fun. And his rationale for his non-traditional working setup is fascinating.

What's in your PC?
My work PC is a Mac Pro running Windows 8.1.

3.7GHz quad-core with 10MB of L3 cache
12GB (3 x 4GB) of 1866MHz DDR3 ECC
1TB PCIe-based flash storage
Dual AMD FirePro D700 GPUs with 6GB of GDDR5 VRAM each

What's the most interesting part of your setup?
Probably the fact that it's a Mac Pro. It looks like a bin.



What's on your desk?
Mac Pro, 2 Apple Displays (connected via thunderbolt), a phone that I never use and a printer.

Do you have a gaming PC?
No I don't have a gaming 'PC'. The Mac is probably more powerful and sexy looking than any gaming PC I could build. I've never had any problems with performance. PC manufacturers have kind of got it wrong for 10 years when designing gaming PCs. I don't want a computer that looks like a motorbike, I'm not 12 years old. I want a PC that doesn't look out of place in my living room. I don't want to have to lock it away in its own room.

At one time I did build a smaller PC with a smaller case, but it was always a struggle to fit everything in, and even then everything was quite loud.

Even though I use a Mac I don't use OSX. This kind of makes me a sinner in both camps. PC users hate it because I'm using a Mac (even though it's just a PC) and Mac users hate it because I'm using Windows.

Blur added to obscure giant Rust penis.

At home I have an iMac with Windows installed. OSX has a tool built in to let you easily install Windows. It's not running emulated, it creates a partition and you boot into it. I have one wire coming from my computer, and that's plugged in the wall to power it.

The only disadvantages to using a Mac are the price and the fact that you can't really upgrade them (except for memory). To me this isn't a big deal because I'm rich as fuck so I'm more likely to just buy the latest model instead of trying to get 10fps extra in BF4 by upgrading the graphics card.

My days of taking my PC to bits to make it faster are over. In the same way that I don't take my TV or fridge to bits and change components. This stuff doesn't interest me. I just want to use it.

What are you playing right now?
Banished.

What's your favorite game and why?
Ever? My favourite game ever is probably Black and White 2. I don't know exactly why but it's a game that I return to and play through at least once a year.

Mr. Newman also sent a picture of his "PS4/XBone/Steambox desk" for inclusion:

You may have noticed some strange behavior in Garry s Mod if you played it a couple of days ago. An exploit that took advantage of the Source Engine s file sending mechanism made it possible to send files with any extension to the client or server. Strangely, this was used to change users Steam name to VINH'LL FIX IT, and using them to spam friends and players with the word cough over chat. The exploit is mostly fixed now, but Garry s Mod s own Garry Newman tells us it could have been a lot worse.
The worm as I understand it was transferred to the client as a dll, then when it loaded it crashed the client, in the hope that they'd join another server, Newman told PC Gamer in an email. When they did it downloaded the server's config file and looked for a rcon password. RCON, or remote console, allows you to control a server remotely. If it got one, it infected the server by uploading the dll and running it (it didn't need rcon to upload the dll, only to run it). And then the cycle continued.
Newman said he patched Garry s Mod within an hour of finding out about it, and that Valve did the same, but that it s still possible for the bug to spread via different Source Engine mods, so be careful what you download.
The effects of the worm were mostly non-destructive as far as we know, Newman said. Luckily the creator kept it pretty tame. It could have been a hell of a lot worse. I hope by being proactive and patching it quickly we avoided anyone using it maliciously.

Have you played every single game in your Steam library? No? Neither have I and that accomplishment is apparently just a small sand grain in the over 288 million games in Steam collections that have never felt a press of the Play button. That's a surprising figure from a new report by Ars Technica researching the most active and popular games on Steam straight from the recorded statistics of some of the platform's 75-million-strong community.

Ars' method for its number flood involves sampling registered games and their played hours via profiles and their unique Steam IDs. With the help of a server for computational muscle, Ars randomly polled more than 100,000 profiles daily for two months to pull together an idea of which games see the most time on everyone's monitors. In other words, your Backlog of Shame (don't deny it, everyone has one) probably took part in some SCIENCE at some point. Exciting.

Some caveats exist, though. The data Ars looked at for its research only extends back to 2009, when Steam brought in its "hours played" tracking system. Owned and played/unplayed games are thus slightly skewed to not account for older releases from the early noughties, and any length of time spent in offline mode wouldn't get picked up by Steam either. Still, Ars claims its results deliver a good picture of Steam gaming trends for the past five years albeit with some imperfections.

Predictably, Valve's personal products stack high on the list in terms of ownership and most played hours. Dota 2 takes the crown with an estimated 26 million players who ganked faces at some point in the MOBA, but free-to-play FPS Team Fortress 2 follows closely behind with a little over 20 million users. Counter-Strike: Source rounds out the top three with nearly 9 million players, but it's also collecting dust in over 3 million libraries.

As for non-Valve games, Skyrim wins in activity, barely edging out Counter-Strike: Global Offensive with 5.7 million estimated active owners. Civilization V kept 5.4 million players hooked for Just One More Turn, and Garry's Mod boasts 4.6 million budding physics artists.

Want to know what the most unplayed Steam game is? It's Half-Life 2: Lost Coast, the Source tech demo given free to pretty much everyone on Steam who bought or fired up Half-Life 2. It hasn't been touched by an approximate 10.7 million players. I guess that old fisherman is feeling pretty lonely right now.

My favorite stat is the total of played hours divided by game mode, more specifically the separate multiplayer clients of the Steam versions of Call of Duty: Modern Warfare 2 and Black Ops. The single-player campaigns for each respective title sits modestly within the mid-20-hour range, but the multiplayer side balloons well into the hundreds of hours. It's a pretty obvious indicator of where the biggest chunk of popularity resides in FPS gaming, but it's not like you wouldn't get weird looks for claiming you play Call of Duty for the story anyway.

See more of Ars' results in both number and pretty orange graph form in its report.

So far in Rust, I've encountered rock-wielding bandits, malicious architects building one-room death arenas, and a cult of naked men. Poke around the community for a bit, and you'll find more good times in a game with such a sheer degree of freedom. Those flashes of spontaneity are just a small part of why Rust is really cool. Its success is, by now, not a big surprise after a pretty strong early access alpha and taking the top spot for survival RPG player activity, but today marks another notch in Rust's handcrafted leather belt: it's sold over 1 million copies, as tweeted today by Facepunch founder Garry Newman.

As a comparison, it took Garry's Mod a little over five years to hit the same sales milestone since launching on Steam in 2006. More impressive is the fact that Rust is still in alpha, with Facepunch continually tweaking and updating the game as it nears a full release. Rust first arrived on Steam Early Access on December 11.

Last week, Facepunch pushed out a sizable patch that removed zombies from the game entirely and improved animal behavior beyond derp levels. A million sales in almost exactly two months--not bad for a WIP title with a warning line of contains violence and caveman-themed nudity."

We've got our own thoughts on Rust's alpha right here. If you're jumping in for the first time, check out our guide to surviving your first day.

Humble Jumbo Bundle. That's quite a mouthful, and if you say it ten times fast it will summon both Beetlejuice and Candyman and open a portal to the underworld. So, y'know, it's probably best to avoid that. However, it's also the name of the Humble Bundle's latest pay-what-you-want sale, which this time discounts Sanctum 2, Magicka with two bits of DLC, and Natural Selection 2. Beat the average and you'll also get Orcs Must Die 2, Garry's Mod and Serious Sam 3: BFE throw in too. If your bank account wasn't summarily emptied during the course of the Steam sale, it might be worth a look.

That average, at the time of writing, stands at $4.10, so you won't have to fork out much of your pay packet/poker winnings/pocket money to get your hands on those six games. The charities receiving some or all or none of your money this time are Watsi and Child's Play, and there will of course be more games added to the deal over time.

The Humble Jumbo Bundle ends in a little over 13 days.
