META UHC started off as a datapack I wrote in high school to play UHC with my friends on lunch breaks. For this reason it’s designed to be super quick to configure, and games can be configured to last between 5 and 120 minutes. The best part is that it’s a datapack and not a map, so you can drop it into a world with any mods or custom worldgens you want, and it’ll work out of the box!
To use this datapack, simply add it to your world and run /function admin:setup, and you’re good to go.
