I built Darwin Australia map and a mission for it (Japanese attack in WW2) 4 years ago but we couldnt do it as a multiplayer mission bc WT CDK didnt have the ability.
I’m wondering if that has changed yet.
While youre at it. Check out my profile and grab the map and mission… its damn good
Custom made maps or maps with user created vehicles are still unable to be played in multiplayer. At least in the custom game browser.
