So it just kinda clicked to me that the bodies floating to the bottom in ED3 might be a reference to Bodies by Drowning Pool
i.e. the Bodies are in a Drowning Pool (ED3)
Unfortunately not, but I like this as an abstract retroactive reference.
There are a few Enter Shikari, Bring Me The Horizon and various other alt/metalcore references throughout the elite dungeons though. Mostly purposefully vague and thematically appropriate so as not to be jarring.
