A newer and updated version of my map Symmetry. Still a great 2v2 and 4v4 slayer map and is also a great map to play SWAT. Base A: Base B: Snipe B: Snipe A: Download map at http://www.bungie.net/forums/posts.aspx?h3fileid=29786854
Sorry, I honestly would love to see your map, but happen to not be on your home network (only for a while mwhaha), so therfore I cannot see your screenshots.
I think I know how you messed up with your images. Try using imageshack, upload them, use the hotlink for forums code. If you use the IMG tags it has to be off of a webpage, like you find on google image search. You used where it is located on your computer, and that simply doesn't work. Use imageshack, or get it on a webpage or it wont work, I suggest imageshack or photobucket.
The open are looks too open, I don't see any interlocking (it could need it), and the map looks a little sloppy. How about a description of the things in the map or a weapons list?
