I have recently discovered a glitch that allows you to get out of bounds, it also allows you to skip multiple areas in the game Example:

intro (timestamp) 0:00 skip waiting in line (20sec)

chapter 1 (timestamp) 0:55 skip spying on Bellick (90sec) skip shower fight (15 secs)

chapter 2 (timestamp) 2:17 skip fight scene (10 second) skip vent in asylum (not sure if faster)

chapter 3 (timestamp) 3:16 skip all of the asylum (60sec)

chapter 5 (timestamp) 4:16 Skip from start of chapter to cutscene(not been timed) Skip guard (harder difficulty)

chapter 8 (timestamp) 6:31 skip Bellicks and Pope (Guppy Only) guard skip shu (not timed)

Probably a lot more to discover. Link to video:

new video with more skips

finally found a new skip in chapter 7 unfortunately its hard to set up the clip to get oob

it saves:

talking to Geary

entering laundry room

getting card in the laundry room
