So while hunting for the other patreon easter eggs on a couple of my games I've had this model of the navy seal from Black Ops 2 spawn in the air just before the weapons fridge. Not far from him is a floating KN-44 as well. It's listed as a map object which leads me to believe it's part of another EE. At this time I don't know what though.
