Chicken Invaders is the first game of the Chicken Invaders franchise, released on 24 July 1999. It is a fixed shooter, reminiscent of the original Space Invaders (of which the game is a parody of), in which the player controls a lone spacecraft by moving it horizontally across the bottom of the screen and firing at swarms of invading extraterrestrial chickens. The game features both single player and two-player game modes. Known also as the DX Edition, it is a reimagined, 3D version of an earlier, unfinished DOS version made in 1997.
