ok, so here is the arena as it stands: It is cube shaped, consisting of 8 rooms, a layer of 4 on top, and a layer of 4 on bottom. Kinda like a rubic's cube but with rows of 2 rather then 3.
If you're looking down on it, it would be set up as follows.
Upper level, top left: A bridge with 6 swinging pendulum blades. It's not a straight bridge, it connects to the rooms adjacent to this one, so it has a kind of right angle shape. This bridge is over open air, and this room "empties" out into the room below it. Ie, if you fall off the bridge here, you fall into the Lower level, top left room.
Upper Level, Top right: A Japanese zen garden. Like
This. Large standing stones to hide behind, but otherwise just nice white sand for you to mess up.
Upper level, bottom left: A zero g room occupied by lots of floating, black stone spheres that have some resistance to momentum.
Upper level, bottom right: This room contains what appears to be a complete replica of a cityscape, with the tallest skyscapers in the center being about the same height as a man. The center of the room is dominated by a downtown area of taller buildings and skyscrapers that smooths out into inner city areas and then suburbs and finally mostly empty fields on the outskirts.
Lower level, Top left: A Deep pool of water. There are large, rectangular slabs extending from the bottom of the pool up to just above the surface of the water, forming stepping stones that are scattered randomly about.
Lower level, Top right: A room filled with random scrap, like a junkyard. Mostly metal scrap with some glass, rubber, rubble and various other things thrown in.
Lower Level, bottom left: A field of yellowed tall grass with a large willow tree in the center. Dozens of dead men hang from the branches.
Lower level, bottom right: A large, library like room, with the floor lined with rows of bookshelves and two higher levels of shelves that are lined up against the walls. Something like this:
Each room connects to the three other rooms adjacent to it via either a simple doorway, or shaft and ladder cut into the stone that makes up the walls of these rooms. Each room is quite large, a good 100 feet square.
Does that make sense?
