Ben 10: Alien Force -- Vilgax Attacks (US Version) Nintendo DS

In Ben 10: Alien Force: Vilgax Attacks, players will experience an action packed adventure in the vast Alien Force universe, as they take Ben and the Omnitrix into outer space and alien home planets for the first time ever in the series. In an original storyline developed exclusively for the game, Ben will use ten of his alien forms -- Echo Echo, Goop, Brainstorm, Chromastone, Big Chill, Humungousaur, Spidermonkey, Swampfire, Jet Ray, and Cannonbolt -- and their special powers to battle his greatest enemy, Vilgax and an extreme team of fearsome foes in an effort to thwart a grand scheme to conquer the universe one planet at a time. Players will also get to journey to never-before-seen planets in an upgradeable spacecraft while blasting through asteroid fields and enemy ships.
