Guns is a realistic simulator and game, in which you have the commando and are able to choose a lot of different weapons and look at them from every angle: Assault Rifles, Sniper Rifles, Rocket Launchers, Handguns, Shotguns, (light) Machine Guns, Sub-Machine Guns, Minigun, etc.

Try each weapon out and shoot down the different objects/targets in the games environment like you would be at the frontline in the real world (Xtreme war scene/battle field). Score as much points as you can.
Tap the screen to fire and use the joystick to aim at the objects.
