A baseball diamond. Check the locker room for the really big guns. Not a new map, just new to this page.
For such a small map, it sure is easy to get lost... Contains Harry Hahn's impeccable attention to detail (check out the Marathon logo in the big room near the top of the map, done in lights...) Not a new map, just new to this page.
Kind of like a motocross course. Very pretty to look at, some of its features may not be quite so fun with someone chasing you... Rearranged a bit to facilitate flow. New version actually gets the invisibility regenerating...
Personally, I like a little more room to move.
