1st floor and basement are done. That's it for now (unless I expand the map).
The 1st & 3rd floors have been totally changed from the original. Most of the other floors have been modified. The basement is the same at the moment but I may change it around and make that the starting point + add some cells and padded rooms down there. Maybe a few tunnels.
Pretty happy with the end result. I think it's already 10 times scarier than the original version. I actually used to urban explore these places as a teenager ( https://www.youtube.com/watch?v=cFZztn8c2cM ) and I think I'm pretty close to the real thing in terms of textures
I haven't added the new area yet. But I may use it for after you cross the elevator shaft. Not sure yet.
Next step is decorating: furnishing, pipes, electrical lines, graffiti. Also need to finish the stairways.
