Based on the innovative PlayStation original, this PSP edition of Ape Escape sets loose a whole new round of siren-helmeted simians, and challenges players to catch them all before they rewrite history to put themselves at the top of the evolutionary ladder. In the role of the absent-minded professor's plucky companion Spike, PSP gamers must use stealth tactics and an array of goofy gadgets to capture more than 200 escaped monkeys, hiding throughout more than 20 levels on eight historically inspired game worlds. ~ All Game Guide
