This has been buggin’ me. In Atlas HQ there is a room with 2 walls of lockers. *The room with the fast travel station near the exit to Meridian Meteoplex.
You pass through the room right before your fight with Katagawa Jr.
So there are 2 stacks of lockers (3x5 each) and some are locked, some are not. Each wall has 5 unlocked lockers. I cant help but think this is some sort of puzzle (or I just haven’t progressed enough and they all unlock later). But I wonder if we open the unlocked ones in some order, then all of them will open. Or maybe there’s another way.
