Had 3 games where gas leaks started the second we got out of the elevators. 2 of them happened on maps with stuff like fire in the way, Resulting in losses whilst we scrambled to find fire extinguishers to get past the fire. so either make the timer longer, or make repair faster, maybe with a item. or add a delay so gas leaks cant start for X time from a level start. Maybe a combo of the three.
