Interestingly, this isn't the only Q3 level that was built to demo nvidia's Geforce 2 chips around this time. Mathias "TheUnreal" Neumann also created 'Creative 3D Blaster GeForce 2 GTS' (3dblastergts.pk3) released 06-26-00 to show off Creative's implementation of the chip. His level is also finished to a high standard but demonstrates things in a far more direct manner, having multiple corridors to show off multiple rendering pipelines and such.
Bit of a strange time for corporate content creation in q3, all told.
