I redid some rooms and got rid of a few weapons and half of the equipment.
This Map is named after the Cube (cube = regular Hexahedron) I have as a center piece. The walls are raised enough so you cant jump out. great for free for all and team slayer.

Rocket spawn (every 2 minutes) i changed a little in this area. added a platform so you can jump onto the cube easier. and added another platform down the ramp so you can jump up to the South Deck.

3rd level of the 3rd building and the spiral ramp. (ramp may look bumpy, but nothing that interferes with gameplay) small balcony lets you look over the green room.

This is the other half of the bottom of the 3rd building. (right at the bottom of the spiral ramp. entrance to green room on the left). the picture is viewing as if you just left the teleporter.

shotgun room, changed 2 things, added in that column and made the ramp up from the green room smoother. This room connects into the 2nd building.

upper level of the 2nd building, door on left takes you to the north deck. Teleporter in back takes you to the portal under the spiral ramp. Needler spawns in back right corner. I added in the wall and cover because this room seemed bare before and other recomended (thx AARC Forgers [winking face]).

bottom level of the 2nd building. I added in some walls and made cover down around the brute shot spawn. This room links into the back alley that leads to the 1st building.

The 1st building. This picture is taken from the ramp that leads into the back alley. the ramp that is visible on the left leads to the north deck. (Note how awesome the blue guy {Astroturd} looks)

This is the North Deck, where the firebomb grenade spawns. it links the 1st and 2nd building together. I added in the columns to help enhance the look and provide cover below and smoothed the deck to make a level walking surface. The entrance to the Back Alley is visible under the Deck.

I hope you like the changes, please continue to share your thoughts on the map. i would work on making it look better if the stupid game would let me use more items.
