Making maps public
Once you've tested your map and are confident that it is perfect, you can make it public so anyone can play it.
First, you should review the map requirements to ensure your map is high enough quality so that all players can enjoy it. It's important to put care into maps before making them go public. Every map version that gets made public must remain around on Warzone's servers forever, since games that were created on that map also stay around forever. Therefore, it's best if every effort is put into maps to try to make them perfect before they get upgraded to public.
Once you've reviewed the map requirements, simply click "Change Map Mode" and select Public, just like you did when making it testing.
Please note that it may take some time for your map to become visible to all users. This usually takes less than 24 hours, and it can take longer than that when volume is high.
