3 solo levels, not a full scenario (the levels aren't linked together), and still in alpha phase (according to the author). Guess he never got around to finishing it...

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.
