A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Fixes and Updates Security fixes to client/server file transfers Fixed "Out of thread ids" error when launching Alien Swarm on a computer with 32 or more logical processors Updated localization files
The best free games are on PC, and if you want to know what the best 50 are then you’ve come to the right place. …
Have You Played? is an endless stream of game recommendations. One a day, every day of the year, perhaps for all time. Valve have a game even more forgotten than Ricochet. Despite being only five years old, I bet if I’d asked you to write down all their games you’d have missed off Alien Swarm . …
MOD OF THE WEEK In Mod of the Week, Chris Livingston scours the world of user-created adventure for worthy downloads. This week, a mod that turns one of the best shooters ever into an RTS. Lambda Wars (originally HL2 Wars), a real-time strategy set in the Half-Life 2 universe, is a mod years in the making and has now had an official launch on Steam. This mod of Alien Swarm provides a bird's-eye view of the struggle between the Combine and rebels and includes both single-player and online play. The world of Half-Life 2 is perfect for a translation into cl
Half-Life 3 it ain't, but if it's a new Half-Life game you crave then maybe Lambda Wars will do the trick. An RTS spin on the Half-Life universe, Lambda Wars has been kicking around the modding community for a while as HL2: Wars, but now it's absolutely standalone and most winningly, free. The beta has been available since the weekend. The game uses the Alien Swarm engine, but as a newly standalone offering you won't need a copy of that nor any Source Engine game to run this. As either the Combine or Resistance you can play online with up to eight human or AI players.
Well that was quick. Ikaruga only shot its way onto Steam Greenlight the other day, and it's already emerged from the other end of the Valve's giant approvals machine, covered in a viscous, sticky substance it's probably best not to investigate too strenuously. It's joined by 36 other assorted things (most of them games), including sci-fi roguelike Steam Marines, platforming roguelike TowerClimb (not to be confused with Towerfall), and lots of other things that aren't roguelikes - if you can imagine such a thing. The full list is below. There's some great stuff in here, including action-horr
3761 AD. Seattle. A line of tourists is snaking around a wrecked skyscraper. If we listen closely, we can hear their guide: “… this is the cupboard where they found the ‘test heads’, and this is where they arrested Robin “Mad Hatter” Walker, who admitted to 243402 counts of decapitation. That’s the rebuilt Dota 2 annex. The war where the Dota 2 team attempted to secede from the union in 2103 caused a brief civil war, but it turned out their tactics when applied to a real world conflict just got them all killed. We don’t know what this place was:
Valve are currently beta testing a selection of additions and changes to Steam's Community pages. Not only have they separated out general community activity from your own contributions, and created a Community Home as an all-game version of the Game Hubs, but you can also upload artwork for any Valve game. It's not all charmingly crude MS Paint scribbles, though, as Valve's artists have created an installation for this digital gallery, featuring concept, prototypes and posters for everything from Portal to Dota 2. Artwork can only be uploaded for Valve games right now, with the rest of Stea
Games get a bad rap for being a solitary, violence-obsessed form of entertainment. But they can also be a collaborative, violence-obsessed form of entertainment. Just ask the close-knit PC Gamer team. Tom F: Co-op based games teach us the value of teamwork better than any kitten based motivational poster, by showing us how many more of our enemies we can crush if we can just learn to work together. Graham: They’re not just violent either. We can build giant penis statues together in Minecraft. No, wait, that’s bad. We can control egotistical millionaires in FIFA! Oh God, no. Rich? Rich: Well
- Added latest localization files. - Fixed a crash when viewing the Achievements screen in a non-English language.
- Added shader source code. - Matchmaking system supports mods with more than 4 players. - Mods store their config.cfg separately from the base game.
Concept art is often beautiful, but even with a growing number of art books being bundled with collector's editions, it's just as often work that will never be seen by anyone outside of a game's development team. The Into The Pixel collection tries to change that. Organised by the Academy of Interactive Arts & Sciences and the Entertainment Software Association, each year it selects some of the best pieces of gaming art, whatever the reason for its creation. The 17 new pieces to be displayed at this year's E3 have just been released, and I've posted the PC-relevant images below, includin
Every month, we present you with a roundup of the best free PC games that have been recently released. What we haven’t done before is sit down and think about all the best free PC games knocking around the internet at the moment, eventually formatting them into a big old list feature. We think it’s about time we sorted that out. Like PC Gamer’s annual Top 100, this isn’t supposed to be a definitive declaration of the best games ever. It’s a collection of titles that we think you should be playing right now. A snapshot in time, if you will. So at this moment, in May 2011, here’s our favourite
