A GAS MASK could be useful around these parts. You decide it'd be in your best interests to take i- wait fuck.
The mask just ran away...
Oceanstuck: "eye the gas mask suspiciously and/or wonder what its doing here and/or put it in your infinitory"
Jeffory: "put it on. Nothing ever goes wrong when you put on masks"
JosephOfGlass: "Put it on. Who knows, the fungus' toxins might be floating around in these vents somehow.You can never be too careful."
nintendocs: "Take the mask in one way or another, and hopefully, there is no one else wearing it."
nintendocs: "Also, try to find think of a way you might (somehow) remember that can turn off the fans in the vents, that way you can travel to new areas."
THE MASK JUST RAN AWAY.
YOU RIGHTFULLY FOUND THAT MASK.
You chase the mask a way through the vents, but lose it after it makes a sharp turn. Clever little mask. It has led you right next to one of the MAIN SHAFTS.
You never really ventured into the MAIN SHAFT that often, but this MASK has you intrigued.
The MAIN SHAFT goes from the BOTTOM of the bunker to the TOP HOUSING FLOOR (this floor), supplying the entire facility with fresh air and air conditioning. You're not quite sure how you can turn off the fans, but you always figured the controls were behind that door. It must be some kind of maintenance room or something.
Might as well take a look, you don't know where else that MASK could have went.
You carefully make your way down to the door.
That giant fan always made you feel dizzy.
This door requires a CLASS C KEYCARD to open.
You don't have one of those on you right now, so you'll need to figure another way to open the door.
