The Mechanix Union, frequently abbreviated as MXU, is a Doom mapping group primarily for Zandronum. It was born out of the late clan Machine Shop in late 2010, with a formal date of conception on February 14 2011. MXU primarily makes multiplayer mapsets and mods. Maps made by its members have been featured in major compilation sets such as Duel40, the IDL and WDL CTF packs, as well as featured in various tournament games and community events. MXU is a loose-knit group, with members coming and going throughout the years. Thus members are not listed here, only the leaders who have been consistent since the beginning.
