A 3-level solo scenario. As the author says, the plot's a little hokey, but the levels are quite well done. (I've got a pretty big gripe with the last level... if you leave the tower, you can't get back in. There's a door, but it's only one way... You've got to restart from a saved game, and I didn't have one.) Watch yourself when you're close to a goal... the baddies have a nasty habit of showing up at the last minute.

A map set up to test hairy physics models. It's you against way, way too many baddies... load up your meanest physics model, and see how long you can survive.

A three-level demo of a 10-level solo scenario. (The first level has been altered a little from the original Baraka demo.) Also included are three net levels, as well as lots of peripheral info... a silly movie (you'll need a tool that can make it visible, like ResEdit), screen shots, sketches of work and info on the mapmaking process. Fun, but it seemed to go by pretty quickly...

Tycho didn't die when his ship crashed... and now he's back, and he's pissed. He wants you dead. The levels here are not easy, but they tend to be tough not because of good planning, but because of overwhelming numbers of baddies, and lack of ammo. 6 or 7 blue hunters at a time, e.g. Update adds much better term text, a new level, and some tweaks.
