Ben 10 managed to get some rest in the summer, apparently the evil aliens also took a little time out and did not attack the Earth. But the rest time has passed and the first uninvited guests have already appeared on our planet. Ben received a message that several giant worms of apparently unearthly origin had been sighted in the Grand Canyon area. Go to the place in Ben10 Hero Time and, reincarnated as a hulk named Core, start searching for worms. Collect gadgets along the way, break stone barriers by pressing the Z key. The core is very strong, but also vulnerable, if he does not have time to strike the worm first, Ben will again become a man and the mission will be failed in Ben10 Hero Time.
