Sort of an advanced, sped-up version of the old Atari Combat cartridge. Each wave starts with a number of opposing tanks and a number of obstacles. One shot will kill you or your enemies, but you have a shield with a limited amount of power. As the game progress, some enemies get shields too. Explosions from killed tanks can destroy other tanks, and much more points are earned from tanks killed in this fashion, especially in a 3 or 4 tank chain reaction, as each subsequent one gets more valuable. Your own destruction can have the same effect if a tank is too close to you, possibly resulting in a large amount of posthemous points!
