How do you made it? TELL ME!

Say please?

Euhm, create a map, keeping in mind the perspective you want the player to see the map from.

Add a player_start area and rename it "CameraPos"
It must be typed exactly as CameraPos, otherwise you will not be able to load the map for the background
Rotate CameraPos so that the z-axis (the blue one) is pointing where you want the camera to look.

Remember: this is a stationary map (the player cannot move around it). Use this to your advantage with billboards and particle systems. Make sure your map extends slightly wider and taller than what your computer screen allows you to see as a buffer zone (a larger computer screen would see more of the map).

Hopefully that makes sense
