Ben 10 makes his PSP debut in this adaptation of the Cartoon Network's hit animated series. Players guide ten-year-old Ben Tennyson across 14 cel-shaded levels as he sets out to stop an alien invasion led by the diabolical Vilgax. To help save the universe, Ben must use his wristwatch-like Omnitrix to transform into one of five upgradeable alien forms: Fourarms, Heatblast, XLR8, Cannonbolt, and Wildvine. Each alien alter ego offers distinct powers needed to defeat enemies, from Cannonbolt's rolling ability to Heatblast's fire control. More than 80 combo moves are available to use in combat, with the developers borrowing the same style of mechanics used in God of War.
