Online Freeroam is a multiplayer mode in Forza Horizon 3 that acts as a multiplayer freeroam lobby allowing up to 12 players to compete against each other in events selected by any player or the session's leader.
In Online Freeroam, players can hang out with other players or compete against each other in events that can be customized with the addition of class restrictions.
Matchmaking
- Online Freeroam - A public online session joinable by anyone at any time. Players will have their own Horizon Group.
- Private Online Freeroam - A private online session that can be joined by invite or if the player and the session leader are friends with each other on Xbox Live. Every player is in the same Horizon Group, and the leader has the authority to kick anyone from the session.
Events
Any event can be accessed in Online Freeroam, even ones that the player has yet to unlock in single player.
When an event is ready to start, players have 30 seconds to join the event and select a car for that event. In case they do not have the required car(s), they can borrow the leader's car from Horizon Car Rental, with the tune included.
Races can be customized to have team races and collisions activated or deactivated. All events can be customized to have class restrictions.
Online Freeroam is the only way that the Drag Strip can be accessed outside of Rivals mode.
