I was playing doom again and I noticed that the energy forms and environments look very similar. A crazy theory is that since time, gravity, and energy are connected, and somehow when we enter into dead space we are seeing a alternate reality where a alternate dimension full of demons that invaded from the argent portal.
Maybe the triglavians and their survival suits are newer versions of the doom slayer suit. maybe A it is the hell dimension, or B it is the earth dimension that got taken over.
WTF am I on?
