Forza Horizon 4 is an open-world racing game and the fourth game in the arcade spin-off series of the main Forza Racing series. This edition is set in a fictitious representation of the United Kingdom. The game features hundreds of cars from numerous licensed manufacturers. Players experience the UK in all four seasons of the year using a dynamic weather system, with each season bringing its own challenge through weather, terrain and specific vehicles.
The game introduces a new feature: a route creator which allows players to create their own races. This version also features real-player racing, where up to 72 players can compete in a synchronised shared world. Players can also play in an offline mode without human racers present.
