Here is some advice: Firstly, delete this map. Now make sure the grid is turned on in BSP. Now remake HALF this map, very carefully, making sure everything is symettrical. Move the ceiling down and the floor up. Also, one reason it won't compile is that you fall straight through the floor, so the floor leaks. Add a proper brush underneath and make the paint actually kill the player. Make sure you use a texture on every surface or it will look horrific. Once you have completed it, mirror it to the enemy base using the mirror feature. Then come back and post again.
