The Heckler and Koch UMP "SMG" is a weapon featured in Nightmare House 2 that is used by the Patient.
Nightmare House 2Edit
The SMG is wielded by Leeroy, Alpha 3, Mike, Alpha 2, and Johnson, Alpha 4 of the Alpha Squad. Prior to an ambush by Creepers, Johnson is dragged away inside a vent. He tosses his SMG for the Patient to use in combat.
