Forza Horizon 4's first expansion Fortune Island includes ten cars. Some cars must be earned by completing Treasure Hunt events across the island.
You'll earn influence towards the Island Conqueror level which can be seen in the stats menu on the Fortune Island tab. Increasing your Island Conqueror level will unlock hints to find the island treasure chests.
If you are having issues seeing your influence level increase on the island try turning your notifications on.
- Open the menu > Settings > HUD And Gameplay > Notifications > Set to On.
