Batman: Arkham Origins - Batarang

The Batarang is one of the basic gadgets that Batman always uses. It is bat-shaped and is used more as a non-lethal way of incapacitating enemies. In addition to that, it can be used to knock weapons out of enemies' hands, as well as make for a distraction for a guard and even hit an out-of-reach switch. Previous games had different types of Batarangs, although it's unclear if Origins will have as many types.
