KGZDoom

KGZDoom was a source modification of the ZDoom Community Build, version 2.0.96x. It introduced several new features that were considered too hacky to be included in the mainline ZDoom repository.

History
A first release appeared on May 28, 2005, implementing support for a class called. Implementation of this allows particle flash effects to be made that operate in a random pattern. A later release in August implemented a flag called, allowing actors, monsters and other things to be drivable as if they were a vehicle. A demonstration WAD, called demonstrates these additions.

The last release was on August 18, 2005.

Features

 * Rudimentary vehicle support for actors, monsters and other things through flag
 * Particle flash light effects
 * A duration toggle to determine how long particles should exist before fading out

Demonstration map
The KGZDoom package includes a WAD called. It features a demonstration map that includes the following:
 * A very large open canyon with various height levels. Several vehicles can be found throughout the canyon
 * Multiple turrets shooting plasma bursts, which can be entered
 * Various helicopters. You can fly these to great heights
 * Several that can be piloted
 * The Crusader from Strife which can fly and travel at significant speeds and demonstrates the then new DECORATE weapon system through its flamethrower

Legacy
kgsws attempted in April 2006 to get the flag included in GZDoom but was dismissed by Graf Zahl because of the hacky and unstable nature of the implementation. A later bump in May by a user on the ZDoom forums generated a similar response.
