Alien Swarm

review: In Alien Swarm, you run around, (40 different weapons.) with up to 3 more players, killing swarms of aliens (shoot-em-up set at a 60 degree angle). There are a variety of different difficult settings, which allows the game to (unlockables and achievements) cater for all skill levels. Lots of achievements to earn.
