Ok, just took a look at it. It's not even at the beta stage. I don't mean to be mean, but this falls under the "first map I ever made and should never be released" category. It's not even vised or lit. The rspeeds are terrible. There's brushes just floating in the air. Very little remotely resembles reality. The brushwork is terrible -- looks like you didn't even use a grid -- stuff is misaligned all over the place.
Take a look at the screenshot -- none of those edges line up on the bunker there -- that causes wasted polygons, looks bad, and makes people get "stuck." Also, transparent bunkers suck.
