A circular outdoor arena, with grandstand seats, and a small but deep (waterfilled) pit in the center. All the goodies (SPNKR, TOZT, powerup canisters) are in the central pit... but good players will be able to take a good chunk of health out of someone diving in - the opening is small enough that you have to slow down to a walk to get in. Better hope you actually kill them going down!

A collection of 5 maps (well, 6 if you count a small opening level for one of the other ones - accessible only in single player and coop).

A pair of maps that share a similar overall layout, but play very differently. Both are loaded with eye candy (Tempest, especially, has some pretty fun lighting effects), and both have a generally square layout with an outer corridor enclosing an inner complex... but the inner complexes are very different.
