Welcome to the Valve Developer Union

The Valve Developer Union was a site dedicated to preserving tools and information about modding the Quake, GoldSrc, and Source engines. At its peak, we had plans to expand out into other retro FPS engines, the support of TWHL veterans and newcomers alike, and an incredibly active Discord server of around 140 people who regularly shared their work and shitposted with us.

Difficulties between its webmaster, Jaxswat, and maintainer, mariteaux, lead to the slow, messy dissolution of the Union. In November 2019, Jax finally transferred the domain to mari, and he put this static site together as an archive for all of VDU's original content, downloads and all. No new content is planned to be added.
