The penguins have declared war on you and are trying to kill you by attacking from all sides. Your mission is to kill all your enemies and stay alive until the wave ends. When you kill a specific number of penguins, you will be able to upgrade your weapons and buy new ones like the ultimate chainsaw, machine gun, rocket launcher and others. Use the WASD keys to move around and the mouse to aim and shoot towards the incoming penguins. Hit the Q and E key to chain weapons. Collect any cash, health or other items left by the dead penguins to help you survive longer.
