[1] Between two and four human and computer-controlled opponents each control one stationary tank in a two-dimensional playfield of randomly generated mountainous terrain.
Players purchase equipment before each round, and bonus cash is awarded for dealing damage to opponents.
Shields include the inexpensive Absorb, which absorbs damage, the Magnetic shield which deflects incoming warheads (at three different levels, from a gentle nudge to seriously altering the inbound trajectory), the X-tinguisher which absorbs most weapons that make a direct hit and puts them into the target's own inventory, the Detonator, which triggers dangerous weapons safely out of range, and Feedback, which reflects incoming direct hits directly back where they came from.
Version 1.00 added computer controlled opponents and four new weapons: the Scatter Shot, Firecracker, Super Zapper, and Chain Reaction.
Version 1.75 added twenty new weapons, the Displacer and Feedback shield types, new death sequences, tank sliding, music by Eric "Sidewinder" Gieseke, and various minor improvements.
