Warheads for Windows

Warheads for Windows is a clone of Atari's popular 1980 arcade game, Missile Command.

Originally it was pretty much a straight rip-off of the classic "intercept the falling missles" game, where you had two missile launchers (instead of three) that you could use to shoot down incoming missiles (the left and right mouse buttons fire from the left and right missile launchers, respectively) to prevent them from destroying six cities below.
