Concentric hallways spiraling out... hence the name. There are shortcuts at some of the outside corners, and at least one secret room. Also comes in a solo version.

This map is a joy, both to look at and to play. Small enough that 2 don't get bored, but big enough to fit 8 without overcrowding. Very, very nice use of 5D space... hard to even notice it. (But it really makes the map work.)

12 maps. Lots of (too) sharp angles, and some jarring texture choices, but there's some pretty nice use of platforms here...

A pretty simple maze, with a somewhat hard-to-find center room. (Much easier if you're not playing this networked... more time.) Nasty Minotaur... but he's not too bad to kill, the first time.
