I got the heretic key and was able to open some keylocks in the slab eventually finding a mask piece and some lore
Im missing a tunnel (above the right bench) its entrance is covered by garbage and rubble so i assume its actually an exit point breakable from the other side and the fact that i can see it is a bug.
Can you please tell me if i missed a pathway or something here in the slab that would lead me there? or if its for later?
Thank you very mucho
