http://i.imgur.com/WwWNZ.jpg I made a giant hollow cube on a 45 degree turn on Impact, nothing serious, just annoying to make. It's fun to use on arena gamemodes like 16 player random weapon madness or what have you. You can download it off my file share, GT: Headsplosion667 On my file share there's Cube (Basic) which is what you see in the picture and Cube (Quad), which has some structures on it designed for 4 team slayer. Quad is not done and probably never will be as it was just something to mess around on; it has no weapons on it as of now. One really cool thing about the map is when structures are placed on it at the same angle of the ground floors of the cube, you can walk up the sides of the buildings. Feel free to use the modify the map as you wish, credit is appreciated but if you don't want to I won't call for a crucifixion.
I saw something like that on far cry 2, with a whole city, it was a really cool idea. very confusing to play as well lol
