This event is hosted in Shootmania and in the title(s) Shootmania Storm. You can participate on your own and registration is not required.
A weekly fun cup organized by the TM North America Discord community. The cup changes gamemodes each week, so join the Discord server to find out what is being played on a given week. The time of the cup is not set in stone. Just prior to the cup is the Weekly Track PotLuck in TM2020. So the NA Storm Cup will always be after that event, in case it goes a little long.
