Oceanstuck: "where else you can reach through the vents? find a way to get the hell out of the bunker that way"

The VENTS should go all throughout the BUNKER.

Through these specific vents you should have access to all the HOUSING ROOMS on THIS FLOOR. There are TWO MAIN SHAFTS on either side of the BUNKER that lead to other floors, but you've never tried to go through them before, what with the giant spinning fans and all.

Nevertheless, you begin your trek through the vents. Though it's been a while since you've last been here, you've still got this place memorized like the back of your hand.

You turn a corner and see... something peeking at you.

It appears to be a gas mask, staring right at you.
