It's impossible for me to review this map as it is one of mine. So I'll just tell you a bit about it :]
Basically there is only one curve (the horn) everything is constructed with brushes. The best way to play it is in a 1on1 or 2on2 game, however a DM match with 4 or 5 is a real fragfest.
Highly suggest you grab this map, and tell me what you think of it - what else can I say? :]
