I never thought of linking the game to someone before. I'm guessing the URL is enough, but if not let me know. I haven't seen a share button anywhere. https://www.warzone.com/MultiPlayer?GameID=33717884
Edit: We are on a 3 day boot, though since I played earlier today I don't think that was the issue here.
