Armor Battle

Armor Battle is a game released for the Intellivision. It was also released as Armor Ambush for the Atari 2600.

Gameplay
You and your opponent alternately control two tanks across varied terrain: one tank is active while the other is dormant, and you can switch between the two as long as neither of them are destroyed. Your mission is to destroy both your opponent's tanks before he destroys both of yours. Be careful of the terrain, because it affects both your driving and your shooting. Use a mine to set up a trap for your opponent, but make sure it doesn't blow your tank up. You both get 50 tanks (25 in the Atari 2600 version) to start with; whoever has the most tanks left wins.
