Ben 10: Alien Force The Game begins five years after Ben put away the DNA-scrambling Omnitrix, but now Grandpa Max has gone missing and the planet Earth is in grave danger. Gamers must help Ben take the Omnitrix out of retirement and lead eight different playable characters—including cousin Gwen, enemy-turned-ally Kevin Levin and five of Ben's brand new alien forms—to utilize their all-new super powers and defeat the intergalactic invaders!
