So if you have been to the Slums there is a Tattoo shop, you must have a Bad Ticket for this, feed the All Knowing Hobo the guy underneath the Don's home.
Feed him till he Mentions a Cheap way into UNA.
Go to the Junk Vendor, at the Shopping area of the Slums, he now sells tickets.
Buy a few or one, then go to the Massage Parlor.
Go to Lin-Lin after paying the Front receptionist, and get a Massage.
Everything should be explained by Lin-Lin there but Basically just bring a Bad Ticket to him and he will fix it up for a Price.
It's a sure way to enter UNA.
