For some time Ben did not receive any messages about the arrival of aliens capable of harming earthlings. He relaxed a little, but suddenly his wrist Ominitrix vibrated, which means that the boy has a new task. It turns out that a group of aliens landed in the mountains and is going to create some kind of dirty trick on the planet. It is necessary to quickly reach and neutralize the saboteurs. The hero will have to use different skins, but first he will move in human form, because it will take agility to jump across platforms without missing a shot in Ben 10 Alien.
