First of all nice map, I've always wanted to create a similar themed map but never got to it :)
Visually I kinda have a problem with your bombsite props - maybe try creating something out of brushes or use custom models instead of the generic bombshells/nuclear waste crates.

I also took some time to find spots where you can get out of the map
Here they are:

Bombsite A, you can get out of the map alone by jumping on the windowframe and then onto the clip brush outside. [i.imgur.com]

Bombsite B, you can get onto the roof of a building with a 2 man boost. [i.imgur.com]

You can get on that same roof by boosting with 2 people on the trucks outside B. [i.imgur.com]

Near T spawn you can get ontop of a building with 3 people boosting each other. [i.imgur.com]

Outside B you can get on a roof with 4 people Boosting each other. (I know who would do that, right? but still ^^) [i.imgur.com]

Outside A you can get on the roof of the swimmingpool area with a 2 man boost. [i.imgur.com]

In mid(?) you can boost onto a roof with 2 people. [i.imgur.com]


please dont see this as criticism I just want to help improving your map, great work, keep it up :)
