Not sure if this counts as a bug or not, might as well post it though.
I went down a staircase to a room filled with Lost Souls, the exit is probably behind a wall but I don't have any explosives, I'm sure I checked everywhere for a break in the wall but it appears that I'm trapped and must restart.
BB Screenshot created.
There is 10mm ammo (x24) lying here.
