ZDaemon

ZDaemon is a source port specificly tailored for online play, originally based off csDoom, which was in turn based on ZDoom 1.22. It has since gone through several major facelifts, and as of its most recent version has vastly improved netcode, a transition to the more updated though still considered antiquated, ZDoom 1.23 codebase. As of now, the ZDaemon project consists of the ZDaemon client itself, a fully featured launcher named ZLauncher, and an server launcher named ZSL. The ZDaemon project was originally started by Nightfang, however he has since given up control of the project to a team of developers that include Raider, Kilgore, Doom2pro and many more. The most recent version of ZDaemon is 1.06. Even the most recent version of ZDaemon has had lag and crash problems with Internet multiplayer.
