About Ben 10 Alien Onslaught
Ben 10: Alien Onslaught is a fast-paced arcade survival game. Aliens are pouring into Bellwood by the hundreds, and the only thing standing between them and the town is a kid with a watch. Survive long enough and the boss shows up: Vilgax in Bellwood, Kevin 11 in the Canyon, and ZsSkayr waiting in the Null Void. Beat them to unlock powerful artifacts, spend your coins in the Plumber Shop on permanent upgrades, and chase 35 achievements. Three arenas, six aliens, fourteen enemy types and three bosses. Easy to pick up, hard to master, and different every single run.
