The gameplay is much like that of Tank Battalion, except that this time up to two (on an upright model) or four (on a cocktail) players can play simultaneously. There are seven new types of enemy tanks (Normal Tanks, Speed Tanks, Hard Tanks, Big Tanks, Rapid Tanks, Tomahawk Tanks and Jeeps) and fifteen types of powerups (Bonus 500, 1000, 2000 and 3000, Shot Powerup, 4-Way Shot, Hyper Shot, Ripple Laser, Twin Shot, Small, Shield, Bomb Attack, Timer Stop, Force Field and Extend) which appear for players to collect in order to increase their tanks' firepower and boost their score. The enemies also roll into view from the top of the screen instead of just appearing and can also enter from the left and right sides. Every fourth round is a "boss" round where the players must fight Train Cannons, AK Tanks and Boss Cannons at the top of the screen as well as the round's regular enemies. The players cannot destroy their own headquarters walls, when one player shoots another they will be pushed back. The game has an ending which will be seen after clearing all thirty-six rounds.
