My favourite non-standard suit that has been available in WoA is the Noir one you could only wear in the New York (“Golden Handshake”) map. It’s the Easter Egg one where you must interact with some portraits in a gallery, obtain and place a golden idol on a particular location then enter a specific crate…
(hoping this new challenge and the Public Enemy suit are formally added soon; it’d work as a temporary substitute on other maps)
Moreover, the 1st November is a day off in some European countries (I don’t know if that’s the case elsewhere). Maybe IOI is off this week and goes back to work next Monday.
