Ben 10 Ultimate Alien: Cosmic Destruction introduces the new alien heroes and challenging puzzle elements. Players control Ben and up to 16 alien heroes including Ultimate Big Chill, Ultimate Spidermonkey, Ultimate Echo Echo, Ultimate Swampfire, Ultimate Humungousaur, Four Arms (PS3), and Rath (Xbox 360).
Ben 10 Ultimate Alien: Cosmic Destruction involves Ben traveling to iconic real-world locations in search of the parts of an ancient Galvan artifact called the Potis Altiare to save the Earth from destruction by an evil To’kustar.
Ben 10 Ultimate Alien: Cosmic Destruction was given mixed reviews, being criticized for its limited length, game mechanics, as well as several gameplay and design concepts. Fans, however, consider this an improvement over past games in the franchise, especially the transformation and combat mechanics having a smoother flow than before.
