I downloaded this one but didn't get to play it tonight (did play your Sky High map though). This is a cool map, arguably your best yet. I like the use of windows and the way you used them to frame, it just looks really cool. Also the layout in this one is simple, super easy to understand and should be very action-packed. I'll definitely run this one next time.
My 360 Map Collection: Suspendead, Curve Damage, Doom Dome, Fatalitrees, Spherikill, Pyramayhem, Valley Ho, No Quarter, Purpose Unknown
don't know if it's my best. each of my maps has its strong points, and the ones I could try played really well.
I think I did pretty well with the windows. I was searching a way to make the map look a bit scifi, and I was hesitating about the windows. I wanted to leave them open, so that you don't lose time having to break the glasses to take your sniper position, but in another hand that looked bland.
This is a pretty decent map, I had a good 16 player game on this today. It reminds me a little of Dump and my map, Moon Rock; in fact I consider it the unofficial sequel.
