What could be better than finally getting a chance to play the long awaited Source Engine version of the Unreal Tournament mod Alien Swarm? An easy answer would probably be getting the game for free on Steam. That’s right; anyone with a Steam account can download a free copy of Alien Swarm starting today.  Alien Swarm is a top-down four-player cooperative shooter that pits players against, what else, swarms of aliens. This free game includes over 40 weapons and equipment, 4 character classes and 8 unique characters, 64 achievements, Matchmaking, Steam Cloud, Steam Stats, and complete game code and mod tools. With the game’s price and included mod tools, you can expect to start finding a host of user-created mods for the game in the near future. Not bad for the low cost of $0. |
