The Curing Clinic is a a section of the Asylum map in SAS: Zombie Assault 2 Insane Asylum, and can be reached via the Rec Centre. It can be unlocked for $500. The M60 can be found and bought here. This area includes two Barricade sections.
This room appears to have some bugs, as zombies can walk through the top-left portion of the wall from outside (sometimes entering the room this way). They also appear to spawn randomly from the inside of the room (near the top barricade).
