The Alien Hominid - The main playable character of the game.Later, on February 28, 2007, an upgraded version of the game was released on XBox Live Arcade for the XBox 360, the service that Castle Crashers would later be very successful on. Ironically, this means that the only major gaming system of the generation that never saw a release of Alien Hominid was the personal computer, where the flash game first became a hit. Later, on February 3 2006, it was ported to the Game Boy Advance, though only in Europe, possibly due to the advent of the increasingly popular DS and PSP handheld gaming systems. Alien Hominid was released for the PlayStation 2 and GameCube in America on November 18, 2004, and for the PlayStation 2 and XBox in Europe in May 2005.
