EyeToy - AntiGrav is a game designed to be played with the EyeToy camera. In AntiGrav, players must move their body to guide their character through steering, speed, and trick maneuvers as they interact with the environment and avoid obstacles. Players can compete against other AI-controlled hoverboard racers, or challenge another player as they race alongside the "ghost" image of their adversary's best performance. The game is one of the few EyeToy titles that were not developed by Sony Computer Entertainment Europe. Harmonix Music Systems, the company behind Frequency and Amplitude, both PlayStation 2 games, developed the game. EyeToy - AntiGrav was released in North America on November 9, 2004, and it hit the stores in Europe on March 3, 2005.
