Alien Swarm

Valve has just released a free game, available right now on Steam, called Alien Swarm. Originally made by independent developers from the Mod community of UT 2004, Alien Swarm was officially developed by the same team, after Valve decided to hire them, two years ago.

The team worked for Valve on Left 4 Dead and Portal 2, while developing Alien Swarm simultaneously. Industrious fellow aren’t they?

Alien Swarm is a top-down 4-player co-op shooter, and it will release with the complete SDK (software development kit) and code base, also available for free. This is how Valve describes the game:
