The Iron Curtain is a promotional primary weapon for the Heavy. It appears to be a Minigun made partially out of wood, with identifiable features such as a Communist Hammer and Sickle emblem visible on the ammo casing and a smoking vent on the side. This weapon was supposedly crafted by the Heavy himself. The weapon functions in exactly the same way as the standard Minigun.

It is awarded to players of Poker Night at the Inventory for defeating the Heavy during a round in which he has bought in with the item instead of cash.
