With an even heavier heart and tears in my eyes nerf pocket internals

For the people who say you can use one Emergency O2 tank all round that's false I have to grab two or three to make it though a round. That's only if most of the station has no air. Maybe I'm just wasteful but I never had to grab one and use only one.

If you fill the tank to 1000 at a canister it will easily last the whole round

Well I don't do that I just grab it and use them. There are so many and they are so easy to find I never needed a reason to fill them up.
