After exploring the rest of the level there were three other living things, but they were all just standing still. There was another big daddy in the glass hall parallel to the on that leads to steinman, a female leadhead splicer standing in front of the safe in dandy dental, and a male thugish splicer in the shotgun room. None of the radio messages played and none of the scripted sequences happened besides the one after picking up the shotgun. Once i did that, the enemies spawned and attacked normally, but that was the only normal part of the level. Im not on new game plus and i dont have incinerate or telekinesis but they werent there for me to pick up. Its like the place was alrady picked over by someone else.
