That’s right, the amazing UT2004 Mod has made its way to mainstream thanks to the help of Valve (bless you Valve for picking up people that deserve it). Amazingly, just as the mod for Unreal Tournament 2004, this will be free to download and play via Steam.

To download and play the game you will need Steam installed. Here’s the link to the Alien Swarm page. Alien Swarm is a Top Down co-op (up to 4 player) shooter with many unique twists. Do I even need to say more. Get you friends and download and play now!
