This is my first map
It's a pretty small map that i think would mainly play outside the main building.
The main building itself has an underground control room, lunchroom and it's where the train pulls in. You can also get on the roof and look over the whole map. The map also has 3 control towers with spot lights.
I must say also that my friend toonquake made the skybox and the train (thx mate)
I think the map would play well with about 8-16 players but no more
