Messiah is a third-person shooter, but instead of a gung-ho space marine, you play Bob. Bob is an angel. He's pretty weak and not much a challenge for his enemies. But Bob has a special gift... he can possess any living creature and gain that creature's special abilities. Possession is the key to Messiah. You have to use possession to fend off your enemies, but you will also need your wits to take control of the right individual to get you past the game's puzzles.
Messiah uses a special engine that automatically generates the most detailed characters your computer can handle every second as you play.
