Chicken Invaders is a series of shoot 'em up video games, developed by InterAction Studios and released for Microsoft Windows, Mac OS X and Linux systems. Currently, there are four video games in the series, along with four special editions.
The main theme of the game is a battle between a lone combat spacecraft and a technologically-advanced race of space-faring chickens intent on subjugating (and later destroying) Earth. The games make heavy use of humour, especially in form of parodies of Galaxian, Star Wars and Star Trek.
