SG Desert & Pyramid
Here is a couple more Stargate related stages. The first is the pyramid from the movie Stargate. It actually has some depth to it.
The second is a custom edit of the UMK3 desert stage.
Stage: SG Offworld
This stage is another Stargate stage. I used a couple of pictures found from their websites and combined them into the stage you see. It has two layers, depth, and that's about it.
Stage: The Dam
