The central arena and the lower area with the lifts between them make a nice combination. Based on the few games I've played, the upper areas around the arena seem to get ignored somewhat. Something feels off about the weapon and ammo placement but I can't put my finger on it. The textures look very bland and it's difficult to orient yourself quickly.
Overall it's a good map but there are a couple similar ones in Cosmic Clouds that I'd probably play instead.
This was my submission for this years map making contest. It is a netmap and you should play it with other people as often as possible.
