Ben 10 Ultimate Alien: Cosmic Destruction — About this game
Use alien abilities to work through side-scrolling fights and platform puzzles. Spidermonkey climbs walls while Humungousaur breaks certain barriers, so changing form matters between battles as well. Watch the lower-screen lessons and match each obstacle to a suitable power. A full special meter enables an Ultimate attack that clears enemies from the screen.
