Real simple. Do you leave the field when you run out of air or paint? Or do you stay on and at least make one more target since the enemy does not know your out.

I made 2 guys surrender sat when I was out of paint and air. They didn't know that. And they didn't want to find out when I tapped them on the back with my barrel. But others will be on the front line. Run out. And just raise there gun and walk off. What gives?
