Hadley Rille on the Moon is the Las Vegas of the future.  the track is on a monorail track through casinos near the Rille.

On this level, I reworked everything including the gameplay,  texture maps, lighting, and geometry.  This level was never finished completely before the game was cancelled.

Neon Sign as seen from the track.  Below is a transporter if you fall off the track.
The lighting on the moon surface was never done.

Here is a closer view of the transporter beam.  

River of Light
I got this idea from O'hare Airport in Chicago.  A lot of this is done with grey textures that were colored by lighting.
