Explanation: you have to align yourself with the middle of the door (didnt test any other positions), get the angle right, jump, drop a jack, drop another jack, THE SECOND JACK HAS TO BE INSIDE THE DOOR AND BEHIND THE PLAYER and the player has to be at least in the middle of the clipped door, then quicksave, quickload, and you are teleported on the other side. It isnt hard to do, but a little bit inconsistent, as you can see I didn't hit it everytime in the vid. Also this makes sub 10 possible on beastking

Can't we just skip through doors with jacko boxes in morbid manor 1 ? Also the start of beast pen 1 is to the left of the exit, if we could find a corner to launch up in the sky with the jacko, we could make it 40-50 seconds faster.
