Zombies vs. Penguins is a physics-based skill game similar to Ricochet Kills. Your goal is to kill all of the zombies in each stage with a limited number of bullets. Conserve your bullets by shooting them so that they ricochet off walls and objects. Not all zombies can be killed with bullets, so you will need make use of spiky objects and explosives to complete some levels. Depending on how many bullets you use, you will receive stars for completing a level. Earn at least 100 stars to unlock Zombie's Revenge, which will allow you to take aim at the penguins.
