``Rayman'' transports players to a mystical world with vibrant animation and an upbeat soundtrack as they help the affable adventure hero defeat bizarre enemies, rescue his friends and restore peace and harmony to the world.
Combining challenging game play, cartoon-like animation and authentic sound effects, ``Rayman'' appeals to gamers of all ages and skill levels. Players explore multi-layered worlds with independently scrolling backdrops leading to clever enemies that learn each gamer's playing style and fight back with wicked skill.
