"Solo Science Fiction Card game with two decks. You control the Mega Tank trying to wipe out the defenders more conventional forces." The Mega Tank Deck contains cards representing the weapons, defenses, and other aspects of the Mega Tank. The Defence Force Deck contains the numerous units which are opposing the Mega Tank: infantry, bombers, tanks, guns, etc. If the Mega Tank loses its 40 armor points, each additional point of damage causes a card to be removed from the Mega Tank Deck. If the Mega Tank Deck runs out of cards, the tank is destroyed and the player loses. If all of the Defender cards are discarded to the Casualty Pile before the Mega Tank is destroyed, the player wins. A game apparently inspired by Ogre.
