Armor Battle is a top-down combat shooter game from the Sega Genesis version of Action 52, one of the most famous multicarts. It is a two player version of the game Norman from the same collection, which itself is a remake of Storm Over the Desert, which is from the NES version of Action 52. In Armor Battle, you and one other player control tanks in a fight to the death in the middle of the desert. Whoever drains the HP of their opponent first wins the tank duel.
