Do you like pimple popping, awesome retro guns, space and zombie-aliens? Good, in ZSG you float around on a meteor in the middle of space and pop zombie-aliens like pimples. ZSG is a fast pace but casual and satisfying shooter with smooth and fun movement, easy to aim guns and squishy enemies that multiply and become faster and faster for each round. The goal is to survive as many rounds and earn as many points as possible.
