Added health and ammo packs to the best of my knowledge, replaced the bridge from floor one to floor two with a choke point on both sides, added a wall inbetween each choke point and right spawn doors, lowered the bottom arena, and opened walls on floor 3.
Thinking of removing the top spawn door, or moving it above the main spawn room, and switching around the ammo and health packs on floor 3, and roofs above the whole area except for the top floor to prevent blast jumping all the way up to the point.
