(Not to be confused with Assassin's Creed Unity.) Unity was a video game being developed by Jeff Minter and Lionhead Studios for the Nintendo GameCube system. It was in development from the beginning of 2003 until its cancellation at the end of 2004. It was to feature Jeff Minter's trademark psychedelic graphical style, meshed with an interactive music component. The music was to be provided by someone who was well-known and appropriate for the game's style, but the participant was never revealed.
