ProtonTank ('Processing Team Operation Tank') is a four-player game, in which a duo controls a tank and has to shoot the opponent tank.
Controlling a tank is done as a team, as each player controls a wheel and the cannon. The tank will fire if both players want to fire and there is no bullet in the arena.
