is it possible to create a custom multiplayer game that has spectators? I would mainly like to run a 1v1 against AI and have human spectators look at it. Is this possible, and if so, how? General info on spectators is also wellcome.
Create the the custom game, ensure the game mode is set to 1v1, add the AI opponent who will join team 2, and finally, click +Player to invite your friends to spectate.
You can right click on players in the game lobby and force them to spectate or nominate them as a referee. Referees are spectators with the ability to chat with players.
