OBSIDIAN is a random level generator for the classic FPS 'DOOM'. The goal is to produce good levels which are fun to play.

Features of OBSIDIAN include:

• high quality levels, e.g. outdoor areas and caves!
• easy to use GUI interface (no messing with command lines)
• built-in node builder, so the levels are ready to play
• uses the LUA scripting language for easy customisation

First, unpack the zip somewhere (e.g. My Documents). Make sure it is extracted with folders, and also make sure the OBSIDIAN.EXE file gets extracted too.

Double click on the OBSIDIAN icon to run it. Select the game in the top left panel, and any other options which take your fancy. Then click the BUILD button in the bottom left panel, and enter an output filename, for example "TEST" (without the quotes).

OBSIDIAN will then build all the maps, showing a blueprint of each one as it goes, and if everything goes smoothly the output file (e.g. "TEST.WAD") will be created at the end. Then you can play it using the normal method for playing mods with that game (e.g. for DOOM source ports: dragging-n-dropping the WAD file onto the source port's EXE is usually enough).

This is a community continuation of the OBLIGE Level Maker, originally created by Andrew Apted.

A brief summary of changes:

Basic support added for HacX 1.2, Chex Quest 3, Harmony, and Hexen.

Hexen map format is supported; in addition there is a translation layer to convert some Doom-formatted prefabs to Hexen format.
