Crossis awesome map!
couple of suggestions worth considering - 2 sniper holes in the wall at either spawn. I put noclip on while I was looking at the map and the two openings could be directly behind the corner pillars on the center area of the middle level, which would prevent spawn snipers - either that or a small wall behind it to keep people from spawning. That would reduce camping either side and make it easier to spot someone hauling ass through a spawn.
Second, how about ladders on each team's side of the big block in the middle with TE on it? Maybe on the sides. I'm sure plenty of people would get knifed being up there hehe...
I like how you made the TE and Crossis shootable
