There was a glitch I discovered about a year and a half ago while fiddling around with Metal Gear Solid 2: Sons of Liberty. This glitch involves going around Shell One when you really can't since Arsenal Gear's launch locked all the doors.
Every strut is the same after meeting Ames, so I didn't check out every one. Also, I'm not sure if this works in the Substance version of the game, because I've never played it.
