The reverse of an escape room...

... is a room you have an hour to break into.

Small Time Criminals, a puzzle room not-quite-LARP in Melbourne that lets you test that old adage about Shadowrun players planning heists for so long that they might as well start robbing banks for real. (Although not the other adage about how all that planning goes out the window as soon as they see a security guard and everybody starts shooting...)
