  1. Minor quibbles aside, this is a must-play game for action gamers, especially those who enjoy playing cooperatively online.

    Totally free, and totally worth your time. [Oct 2010, p.65]
  3. Left 4 Dead minus the Zombies, plus a truckload of skittering aliens. Pure brilliance, and free to boot? Valve knows how to make their customers happy. Get to downloading it, stat!
  4. Download Alien Swarm. Do it, it's an order. It's one of the best freeware games of all times. It's fun, addictive and has great growth possibilities considering how actively the Steam community is already working on it. Thanks for the gift Valve, we love it.
  5. Left 4 Dead top down! Alien Swarm is fast-paced, alien-filled fun that demands cooperative gaming and delivers cleverly directed missions that stay challenging from beginning to the end. The upgrade systems serves as a motivator and the match making is quite good. Physics, sound and lighting convey a spooky atmosphere. Although there is only one campaign at release, Alien Swarm delivers more fun than most full-price games.
  6. Despite the issues of repetition and somewhat contrary design choices, Alien Swarm is an enjoyable shooter at an absolute steal of a non-price.
  7. At least Alien Swarm doesn't try to be anything other than what it is. It's an online action shooter with plenty of things to shoot at.

It runs on the SourceThis 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
