The Piston Pod [Walker (ウォーカー Wōkā ) in the Japanese version] is a futuristic cybernetic enemy in the story mode of Razing Storm.
It is operated by a soldier, armed with laser guns and protected by shields which can withstand multiple submachine gun bullets but are weak against sniper rifle and machine gun bullets. In addition, the exposed robot joints are also weak against sniper rifle bullets. In addition, directly killing the soldier instantly destroys it.
It makes three appearances for a total of six units: in Mona Darta (3 units), in Almada Penitentiary (2 units), and in Lixeira (1 unit).
