I buffed the heck out of it, just because i can. These changes have been applied:
-Minor Camera replacements
-Minor Wall replacements
-Harder Bookcase access, you need to vent and mine an additional wall now
-Changed the Escape route drastically, you now need to bring TWO Stepladders. You`re welcome. (Oh yeah you still need a Tier 3 cutters)
-Double Contraband detectors because i can
-Added 6 Guards
-Floodlights in every cell. Nobody`s gonna sleep well!
-Changed the Exit part a bit, nothing too special.
-Removed the roof of the Job center.
-A LOT more Green doors in the walls for Guards to pass through and ruin your day.
-No more Digging under the Metalwork door. (Well not really, but its a bit harder now.)

Yeah i think thats everything.
