µpak is a map pack that aims to bring realistic, cohesive locations to Kart.
It aims to feature as much cross-compatibility as possible, and includes a special encore gimmick for each map.
Kart Gunmorphing is the kart server you're here for; hosting acro, juicebox, and several votable gametypes.
The KGM repo holds all the files hosted on the server. If you need to cherry-pick something from the addons list, do it here.
