Quake Champions: Doom Edition (QCDE) is a mod that adds game-play mechanics and elements from id Software's Quake Champions to classic Doom. Such add-ons include a huge roster of playable champions from all sorts of boomer shooter games, enemy replacers from Doom 3, Quake, Quake 2 and Quake 4, custom weapons, game-play modes, and more.
It is developed by DBThanatos, Michaelis and geNia since 2018, using a custom fork of the Zandronum engine named Q-Zandronum. The mod includes a fantastic custom soundtrack composed by @MarkieMusic.
QCDE can be downloaded from it's homepage here https://qcde.net/, or from ModDB here https://www.moddb.com/mods/quake-champions-doom-edition
