Rather than a shooting game, Gun Master 3D Online is an arcade game with 3D pixel guns and bricks that requires a high level of physics expertise. To demolish all bricks by firing them is the aim for you. All bricks will continue to rotate around the cannon as long as it is fired. After a shot, the gun will also revolve for a short period of time. I'm glad you'll be able to hit all your targets with a restricted number of shots.
