Tussle Tower
A mostly vertical stage, you're trapped in a somewhat claustrophobic tower - there's springs on the bottom and spikes with a narrow opening on top - the best way to secure victory is to knock your opponent out of the arena through one of the holes in the walls.
Battle Box
This is Chris's favorite. An enclosed space that is only open on the top and in two narrow areas in the side - the area inside the box is wide open and filled with hazards. Aerial combat is a good skill to have here.
Elevator
Simple stage - a large vertical moving platform enclosed by walls on either side, with drop through platforms on the top and bottom. The serene Trophy Gallery music plays in the backgorund.
Battle Wall
Cousin of Battle Box. The arena is divided by a huge wall with a few outcroppings, with floating platforms on either side. It's a must to keep track of where the platforms are, because it's easy to kill yourself by doing your recovery move and missing every platform on the way down.
Open Air Arena
A pretty simple stage - I wanted a stage that was like Battlefield, but bigger. So I made one.
You Have to Burn the Rope
...Yeah.
