incluAlien Swarm free game is a sci-fi action shooter game released in 2010. The game was developed by Valve and made available for free on Steam. Alien Swarm game play is from the top down perspective. Set in 2042, the game takes place on distant planet overrun by aliens. Players control a squad of space marines as they arrive to search for survivors of the invasion.

To do this they must first deliver a thermonuclear warhead into the center of the complex, activate it and return to their ship and leave the planet prior to the bomb exploding.
While not officially mentioned, the inspiration for Alien Swarm appears to have come from the movie Aliens. It loosely follows the plot of the movie with marines coming in to search for survivors and having to fight a horde of aliens.
Alien Swarm can be played co-operatively with up to four players. The game is a remake of Alien Swarm 2K4 the total conversion mode of Unreal Tournament 2004. Developers of the 2K4 mod were hired to work on Alien Swarm as well. As a result, Valve’s Source game engine was used.

In addition, there is multiplayer match making and a map generation tool. The tile based map tool allows players to create their own maps to play and share.
