just a few shapes. you start off in a pool of water and follow a tube until you reach a teleporter. on the other side is another set of similarly default-textured tubes connected by a central lift. it's one of those horrible slow lifts. there's a slightly more hell-themed secret area. eventually you return to the first teleporter, by another (which is totally misaligned with the grid) to find a wall has opened and there's the exit switch.

on the other hand, let's give it a break: this was probably made so soon after BSP had been figured out, and nodebuilders had become available, that any new geometry was impressive by itself.
