Oh...if that's the case I think I'm softlocked. Because the security card in the locker is a level 3 card, right? When I get it and go to security, it says I need a level 3 keycard
Sorry, I never got notified you messaged. In the corner of the lab there is a utility room with a vent to crawl through. Go through that and it leads to the server room which has the level 3 keycard.
