Penguin Command is a clone of the classic “Missile Command” Game, but it has better graphics and music. The gameplay has only been slightly modified.

You have to defend your cities from missiles. You have three rocket launchers: One to the left, one in the middle and one to the right. You can aim with either the touchscreen or a nub set to mouse mode. However, do not mix both, as moving the nub will mix up your touchscreen.
