A really tall tower, a ring around the bottom, and all the good stuff between the two. Lots of fun if you like flying, frustrating as hell if you don't.

Huge. Lots of water, lots of open areas, lots of very, very narrow passageways... horrendously slow on a Q800 at minimal settings. Plan accordingly.

Three levels, all quite a lot of fun. (Swiss Cheese, especially...)

An open arena with waterfilled launch tubes. Now comes in two versions-one containing fisheyes and one without. (Who says feedback gets ignored?). It's a bit slow on non-powermacs, but it's still a blast of a level. The more, the merrier!
