Penguin Massacre is an arcade shooter that lets you play as a penguin defending his base by shooting all the other penguins trying to take it for themselves. Penguins will protect their nesting grounds no matter what, so give a penguin a gun, and it'll shoot everything that even tries to take what they own. Penguins are really cute, but a penguin with a gun? Now that's super "cool" (pun intended).
Mouse = Aim Left Mouse Button = Shoot
