Armour Crush is a card strategy battle game. Two armies face each other across an arena, and the cards in your hand decide what you can send into the fight.
Your cards sit at the bottom of the screen, and each one has a number value. Higher numbers mean stronger, more destructive units. A counter on the panel below keeps rising, and when it reaches a card's value, you can deploy that unit into the arena. Soldiers also come out of your barracks on their own while your tanks roll forward. Defeat the soldiers your opponent sends, then attack their tower. The game ends when one side's main barracks is destroyed.
