The Structure and Layout of Pathos-II and the Greek Letters (Spoilers?)

[Rapture]

Upsilon A is where you are when the room get's flooded (Right?). So the area is damaged enough to be considered "uninhabitable" (a.k.a = Red)

For the Upsilon B description... any idea what the "[Epipe]" means?



Except for Tau and Phi, the rest are located on probably the sea floor (approx. 100 meters all of them)

Tau and Phi locations could indicate that they are at more crushing depths or near the surface. I'm guessing closer to the surface as I have yet to see any mention to how people are suppose to get down to the underwater facility without having a life-boat connection to the surface.
