The gameplay is practically the same as that of yesteryear: a group of tanks fight for survival in turn-based battles where the last tank standing is the winner. The more units you kill, the more money you can make to buy new equipment. The list of available weapons is really long and includes projectiles of all kinds.
Playing Atomic Tanks is really easy. The only thing you need to do is select the angle of the shot, plus the force and the type of weapon you want to use to attack. Keep wind direction in mind, too, so you don't hit yourself with your own projectile.
