The capture area looks like an interesting blend of close quarters combat and fighting from above. The outside area could do with some work but as you say, its a first beta test so forget about that for now - focus on gameplay!
I agree with n30n, you could very easily expand the area around the building and add some elevated levels.
Have I already mentioned more lighting?
I'll add this map on my russian KOTH Public server
I will give feedback later about your map
This map crashes my local server (and game too) with Source engine error:
Bad brushside texinfo
Also, it crashes my public server.
Time to fix obvious bug, nik.
I think you got all of this during gameday, but I wanted to write it down
Looking sweet! i like the buildings and everything, very nice
