Good shit, good shit. Basically climbed out the holes in the roof, there's another 4 access ladders I need to check out next time.
There are no tunnels at Riverview. ;)
Gotta love the old asbestos airlock and bags full of discarded abatement gear from when they tried to clean the place up, wish I'd gotten some shots as that's honestly the creepiest place in the whole building IMO. Nothing else really screams "doom" anymore, it's almost all just textures and decay thoroughly abstract from the buildings past now.
