An interesting demonstration of a technique that can (usually) weed out the cheaters from those that aren't using cheats in a given solo scenario. It doesn't always work, but it should work enough of the time that you (as a scenario maker) will get much less mail complaining about problems from people who only encounter those problems because they've cheated to a place they shouldn't be. (It was inspired by, to some degree, Jason Harper's Level Detector, and can be similarly used to control where a player goes based on his playing style.) Like others in this genre, most of the information ...

A set of techniques useable by mapmakers attempting to force coop players to bypass areas that solo players need to pass through. Simple, clearly explained, these have some limitations (spelled out in the tutorial), but should work quite well regardless. They are far simpler than either Coop-Only Level Bypass Demo or Counter Revolutionary, both to build, and to use. The platform tags mentioned are the Pfhorte versions, since that's what the author uses. Yet another cool tool to extend the marathon experience...

A tiny program that's been around forever... just lost from this server. It will take a Marathon 1 Music file and split it into individual tracks, saved as quicktime movies.

A large, concentrically built map, with rings of passageways around a central force-fielded square. Comes in two flavors, with the second map being an expanded version of the first. Nice construction, and good flow all around...
