Have no fear, they've taken the alien's arsenal up a notch! You now have seven power-up weapons, which also upgrade your grenades. There is also a charge shot so you can hold down your button and unleash a giant ball of destruction. You can dig into the ground for defensive measures, then reach up and pull your enemies under. Enemy riding and head biting is still intact, but you can now also flip over an enemy and carry him, or throw him in eight directions!
