Ben 10 Vs Aliens

The aliens are attacking, but the world is not defenseless when it come to alien invasion.  No, not referring to those nukes that the world can use during times of needs.  Am referring to Ben 10, who has a lot of experience when it comes to handling aliens. The game is played via mouse and you just need to aim and shoot the aliens as they come out.  Howevr, you should be wary that Gwen was captured so she might appear on one of those ships.  Try not to hit her.
