Regular-sized stage with partial walls, as the stage becomes opened below. There are 2 medium-sized high platforms near the edges.
There is now a large spring inside the ground in the middle of the stage. It can be triggered by having a fighter step on it and do a full jump. When triggered it sends all fighters ontop of it flying high left/in place/right according to the directional input of the fighter that triggered it.
The stage takes place in the sky, on top of an airship of the Air Armada, with the rest of the fleet that can be seen in the background.
