The Heckler & Koch SMG II is a cancelled sub-machine gun that made an appearance in Madness Combat 7.5. Deimos took it from an A.T.P. soldat and killed him with it. He continued to use it until he and Sanford reached the main control room, where it ran out of ammo. In Incident: 1000A, Hank stole it from an agent as he pushed him off the roof.
