ICBM3D

ICBM3D ("Inter-Continental Ballistic Missiles, 3D") is a 3D vector-based clone of Dave Theurer's classic Atari arcade game, Missile Command. You are in control of Anti-ICBM weapons which you use to destroy an onslaught of missiles (and other nasties) which are dropping onto your nation.

The game ends when your cities have all been destroyed. You only gain replacement cities by achieving certain score thresholds during each attack.
