After you complete the 2 Asylum Missions, put on the Orderly costume, and return to the asylum grounds --- The other Orderlys will ignore you, enter the Asylum, where those Ordrelys will also ignore you -- go to the rec room, and you will be able to shoot or kick open the door to Block "C", even though there is no blue arrow under it -- continue into block "C", there is plenty of rubble & such laying around, find your way into the Mourgue room, from there into the Furnace room...There is an Exit door, go through it, and you will find yourself in a fenced-In yard -- with no way out, and....WTF !!
You can't re-enter the Asylum, and you are stuck there, In that yard.....Passing out at 2 AM won't help, you will only wake up there also.........WTF !!!!!!!!
