Behind the Scenes
If you have the Wild Wasteland Trait, when the three Y-17's spawn one will say "Hey, who turned out the lights?" A reference to the Doctor Who episode "Silence in the Library".

Bugs
After entering the building, the player may spawn underneath the forcefield, effectively trapping the player if they do not have the upgraded sonic emitter gun. They must then load from a previous save. In one case the individual came back with an upgraded gun, they spawned in front of the door as was supposed to happen. There is no known cause as to why this happened.

The Y-17 Master Trauma Harness may pass through the forcefield and commence attack, spawning the other enemies upon his death
