The Stupid Zombies return in a 4th installment of the popular series. By now you should know the drill: Bounce bullets off walls and kill all the zombies in each level. Some setups are more obvious than others, but you can’t knock the stupid out of the zombie without the occasional brainy puzzle. A variety of missions will get you accustomed to different weapons. Collect coins in each level to unlock new heroes. If you feel extra fancy you can join the VIP mode to shoot groovy jackpot blocks for extra earnings and enjoy other goodies. It’s payback time!
