ObHack is my name for some modifications Fritz and myself have made to Oblige, a random map generator for the original Doom, Doom 2, and Heretic. It is name thusly because it is a hacked Oblige, and as a tribute to the ObHacks posted to the once-great Usenet newsgroup alt.hackers.

The most current version is 007.4, released by Fritz on December 10, 2012.

This software is no longer supported by me; I don't answer emails about the program, nor do I add features or fix bugs. Fritz is the current maintainer. Support for ObHack may or may not be found here:
