Torque bow

A weapon used in gears of war and Gears of war 2 its like a bow and arrow except the arrow is tipped with an explosive substance which can attach to your opponent and explode causing a one hit kill, although the weapon needs to be held down long enough and when the crosshair turns orange, you then know if you hit the target the arrow will stick, Also if you get an active reload you dont need to hit, if the explosion is close enough it will either kill or down your opponent
