I usually play with the default textures, but not because they look that good (no offense here

This is the first version and it is still a work in progress. I'm not that happy with the sky and I'm not sure about the floor either. The trailer I found had a pretty bad quality, but most of it looked "dark with glowing lines" iirc.
Updates:
*v1.1
-new rim wall
*v1.2
- New sky, slighlty darker
- New floor, brighter for better playability
- New cycle walls, slightly brighter
- Added a readme
*v1.3
- New floor, darker to fit TR2N better
- Edd Keefe's full detail lightcycle added as the default model
