Hmmmm, I used the crappy gas mask, by the way does that cheap green gas mask work at all? If it does that's epic but if it doesn't.....that sucks. I can't tell on my computer because it just lags so bad in gas, just gas. I used to like the old sprites where it was the color of the gas and was kind of see through. Man... Someone please tell me, my tablet is android, and I can't use it, we'll I can but, I don't have it right now so....... Yeah.
