  1. Minor quibbles aside, this is a must-play game for action gamers, especially those who enjoy playing cooperatively online.
  2. Simply put, anyone with a capable PC should download this and try it.
  3. Addictive. Fun. Community driven. Free. Where can it go wrong?
  4. Alien Swarm is a free game and has been updated regularly to try to iron out the remaining bugs (excuse the pun). All things considered, as it stands the game is a little disappointing and falls short of its true potential.

  1. This game, while small, is a great game from Valve that's like a top down version of Left4Dead except with alien bugs. It runs on the Source engine and enables people to make their own maps which is a plus. I like how weapons are unlockable but the default weapons still can stand a good chance against enemies on higher difficulties. Overall, it's free and I can't think of a reason not to buy it! Valve sure knows how to cater it's fans with free little gems like this game. Expand
  2. The game lacks content, but it is truly a fun and addicting game allowing customizations and real time tactical game play with friends. and Oh did I mention it's Free? Expand
  3. "Alien Swarm" is a suprisingly fun 4 player co-op game with tons of stuff to do. You will have a good time upgrading and choosing characters and weapons to use for your battle with alien bugs. Oh and btw...It's Free. Expand
  4. This game had the potential to be really great but with valve's continued use of their "matchmaking" software you are not likely to join a server that has a great ping and your options on what maps / settings you play with are almost non existant.

    At least the game is Free and you have more choice than you get with MW2.
