For two player, gray is wasd to move, t to shoot, and f and g to rotate turret. Red is arrow keys to move, o to shoot, and k and l to rotate turret. Note:In two player, turrets move slower, longer waiting time to fire, and cannot move diagonally. Also, when collide in two player, all that happens is the tanks move backwards. This all is designed to make two player more fun.
