How long can a fighter last while floating around in the depths of space? I guess they'll find out if they happen to be placed here. The laws of physics have been tweaked in this battlefield to allow people to exist in space without having to worry about lack of oxygen or vaccume pressure, but there is still no gravity. When here, the sky is anything but the limit. Gravity does not exist in this arena, which means one can land on any of the planets and soar up to bring the fight back into space. On the downside, there isn't much to stop the fighters from flying out of control, so using the lack of gravity sparingly would be a wise decision.
