An attempt to make the perfect net level. Very nice attention to detail (great lighting!), and very good flow. It certainly is a good example of the arena genre...

An arena with a pit. There's an elevator to get out of the pit, but it gets harder to hit after it's been hit once... Comes in two versions, of varying complexity. (One works better on 040's.)

A simple arena with a bunch of teleporters. Be in the right place, and you can take 'em out as they 'port in... Update cleans up some stuff, adds a few tweaks.

Designed to look like-yep, you guessed it-a crossword puzzle. From the included films, it seems to work okay, flowwise.
