Alien Swarm is a free PC title that began life as a Game Mod for Unreal Tournament 2004. Valve, impressed with their work, subsequently hired the team (a la Counter-Strike, Day of Defeat and Team Fortress Classic) and in between helping out with Left 4 Dead and Portal 2, they developed a Source Engine remake of the mod, released on July 19, 2010. The game is played from a top-down perspective.
Up to four players control a squad of Space Marines who are sent to investigate a mining facility on a frozen frontier colony planet that has gone dark. Turns out, it was completely overrun by, well, a swarm of aliens. It could be considered analogous to a top-down Left 4 Dead, although the setting is not quite as bleak.
Currently, the game only has one official campaign titled Jacob's Rest. This raises the question: 'Who exactly is Jacob?'note
On April 20th, 2017, Reactive Drop was released, which officially adds several maps (which previously had to be acquired through mods), up to 8 players (including bots) per map, several new weapons, a death match mode, and Steam workshop support.
