Two years ago, Valve hired the team responsible for Alien Swarm, a top down co-op mod for Unreal Tournament 2004. In that time, the team has been working on projects such as Left 4 Dead and Portal 2, leaving some to think that Alien Swarm may have been abandoned. However, yesterday’s announcement proves that this has not been the case.
In the time since, Alien Swarm has been brought to the Source Engine and had Steamworks integrated. It is also to be released on Steam this coming Monday at the low price of … free.
Not content to release the game, Valve is also releasing the complete source code for Alien Swarm, including the Source engine SDK and Steamworks integration updates.
A promotional video for the new release can be found at the Alien Swarm web site.
