How do you get to that new area
Viewing post in Broken Dreams Correctional Center comments
need to go to the medical area and talk to the cat girl help her find drugs and such and become her assistant eventually she will talk about the drug den that no one knows about then you'll find it in the yard area
(think this is the area you are talking about, basically a dungeon that you play for sport you lose all stats and start from scratch there leveling up as you go don't know if there is a end for it)
The drug den is the newest added area so I am going to assume you mean that. To acces the drug den, you must first complete the initial sections of Eliza Quinn's questline, which involves completing tasks given to you by the task board.
After that, you will become a lab assistant and be given the task of beating up certain inmates to obtain illegal pills from them.
After returning a few of these pills, you will be given access to the drug den at the bottom end of the main floor.
