Step 1 - Find a computer room with a box in it. On the map it is a circular room, with an entrance and an exit.

Step 2 - Hit the computer to trigger the cut-scene that opens the box - Please note, Slash and Eclipse do not work as they don't trigger the cut-scene, and the box will not open.

Step 3 - When you mash through all of the text, immediately turn around, and jump over the box. Turn your character so that they are facing the box. You do not need to be perfectly centered, but you do need to be fairly close to center. Usually If you turn your character around from when the cutscene ends, you dont need to reposition yourself, as it should be close enough.

Step 4 - You should be inside the wall of the box room. Turn around and walk toward the room you were in before you entered the box room. There will be an invisible wall at the corner of the room, and you cannot walk around it, so you will have to jump around it. If you are precise enough, you can land on the ceiling of the corridor as it is really low, but if you cannot make it, you can jump around the corner to the wall between the corridor and the corner of the wall you are on, and there is collision from the floor that extends to the out of bounds location, and from there you can jump to the corridor ceiling.

Step 5 - Make your way to the boss room. Be sure to keep an eye on your map, as it sometimes loses track of where you are, and other rooms do not load when this happens. To fix this, just load and unload existing rooms until the map catches up, or if the rooms you are trying to load and unload permanently unload, reset as the run has died. (Further testing is required, to see about a fix)

Step 6 - When you find the boss room, long jump as far down the corridor on the ceiling as possible, and the cut-scene with the door shutting and locking will play, except you are out of bounds still. Walk to the boss room. For the BDSS-Knight room - walk to the middle of the room, and you will stop as the center is a giant dome. Walk to either side, and follow it around to the middle of the side, and jump off. While you are falling, move your character to the middle, where the red is glowing, and you will fall back into the boss room, no longer out of bounds. From here you can fight the boss. For the Franky boss room - Further testing is required for this room
