Altered Beast is a 1988 beat 'em up video game developed by Team Shinobi and published by Sega for arcades. Set in Ancient Greece, the game follows a Roman centurion who is resurrected by the Olympian god Zeus to rescue his daughter Athena from Neff, the demonic ruler of the underworld. By collecting three power-ups in a level, the player character can transform into one of five mythical beasts. In the original arcade, the end credits are interspersed with images of actors in costumes for the different characters and monsters of the game, implying the whole game was a film production.
