I uploaded it to the beta server.
I can't say too much about the gameplay, as I'd really need to play it with some other people first. Visually, the map looks way too structured/man made to use rock textures, I think. You would either have to do a lot of work to make the rocks look more organic OR you could go the other route and switch things to brick, cement, and/or stone wall textures and make it look more constructed.
The bunkers look very unfeasible as well. Giant, solid, blocks of wood the size of wood the size of a bus don't look natural.
