It has been explore mine adits so many time
there’s a saying, “you can’t go when you can’t see” so many time I was trapped on the mine adits, because those toxic gas has covered all over the place, including stairs
I can deal the toxic gas covered on floors, but if the toxic gas covering the stairs, that make thing lot harder, because I can see jack shit, I can’t even tell where supposed to go
so I suggest if someone can make a blocked stystem on the stairs, to block the toxic gas covering it, I mean in the real life, the gas should be drain out on the exit, make people easy to see, right?
