The Door of Old Habits

[SWCarter]

There's an achievement The Door of Old Habits, which I assume is related to the Key of Old Habits (which you can find on the ground in the staircase room just before the theater part of the mansion). I looked all over for a use for the key but never found it. Does anyone know where the door is?

yep. It is a bit hard to explain , but near the entrance to the casino ( the place with 2 statues and and a Sexy Brutale sign ) , there is a door to the left. Go there , and you ll find another door.

Alternatevely , open your map , and look for one sided door.

Bro I feel so stupid. I must have looked for that damn door for hours. I walked through the statue room dozens of times and didn’t notice a whole NEW ROOM appeared. I’m so ashamed.
