I know I'm supposed to go to level 5 Pest control and enter a cave that goes to oxygen control, but I cant find the right cave I think.
Is it in the big cave to the east? if not, where is the entrance I really cant find it :brokencomputer:

nevermind, Im dumb

If u got a repair skill of 65 use the elevator and go to the pest control room as soon as u get out make a left up the stairs and continue from there once ur in the cave make a right
