Horizon Online is a multiplayer suite in Forza Horizon 3 that features three different game modes; Online Adventure, Online Freeroam, and Online Co-op. It is unlocked upon the player completing their first festival expansion at Byron Bay.
Players can enter matchmaking for any of the three multiplayer modes with select variations or create a private session through the Social section of the Pause Menu. Selecting a mode will require the player to leave the Pause Menu and wait for a prompt before they can join a session.
A multiplayer session can only be set up for content either in the base game or an expansion, and sessions in progress can not swap from the base game to any expansions.
Any players that are part of an Horizon Group will be included with the group leader that is matchmaking for a multiplayer session or creating a private session.
