This is a list of modifications and add-ons for Quake 1. All files have been repacked to either include the latest patch, or for better compression. Do you have a mod that's not listed here or want to list your mod on QuakeWiki? Drop me an email.
The gallery brings you interesting Quake screenshots, screengrabs, levelshots and other related images.
