Handy tutorial if you want to create secret door like in the old Wolfenstein 3D.

A 6-level (well, a few more, but who's counting) map containing tutorials on making a slew of cool effects in Marathon. These range from trivial (more realistic smoke contrails via a single change in the physics model entry) to seriously complex (swinging doors, breaking windows, exploding walls). You even get tasty bonuses like a real laser sight and a working flashlight (this is too cool for words). It's all described in easy-to-follow language, and shows off some of Chris's amazing Killing Time artwork. Absolutely worth a download, for all scenario makers. Upgrade adds curved archways, ...

A short tutorial and a demo map showing how to make user-controllable teleporters... that is, teleporters whose destination is configurable by the player. Pretty slick... download it, use it in your scenario, give Jägermeister credit, and make your players happy.

In the hopes of increasing the overall lighting quality of released maps, the author has created three preset collections of lights, allowing for more variability in level lighting. The enclosed example map also shows how to use some of these. If folks actually take the time to learn the basics of lighting, levels will look much more realistic. This small package can help.

Jesse Simko, creator of the eagerly awaited Muerte Machine, has uploaded this nice demonstration showing how to remove half of the warping effect which happens when a player changes levels. (He's eliminated the warp out effect from the start level... but not the warp in effect on the end level. He does, however, give some suggestions for diminishing the latter effect.) This should be very useful to anyone creating levels based in universes where teleporting makes little sense (Earthlike scenarios, for example), or to someone who's looking for a way to get around the 1024 poly limit on a si...

Force fields have been around since Fm created them in Seige of Nor'Korh, but they've been one-sided (That is, they work from one side, but are passable from the other).

Then Jeff Swartz created dual sided force fields in an award winning map for the Evil Map Making Contest called "FireCracker".

Here, by Michael Watson, is a description (and demo map) showing how to make two-sided forcefields. Nicely done.

The spoiler guide for Tempus Irae 2: The Lost Levels. Lots of useful info and insight from each level's creator. Inexplicably not here before now. (It was created almost 3 months ago.)

Have you ever wanted to allow players to destroy walls, or other types of large environmental objects? Here's a tutorial that shows you how to do it. Perfect for the scenario maker who wants a spectacular effect in their project... (I actually had to redownload An AI Called Wanda to make sure a similar effect wasn't used to make the hull breach in Station Alpha (the sequel), but it seems that was just a hole. I have a recollection of it not being there when I started... but there aren't any platforms in the area. As far as I can tell, Mark's come up with a completely unused technique... a...

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 ...
