It’s appearing quite a while after the September release date, but a Forza Horizon 3 demo is now available on PC. Turn 10 and Playground eventually managed to confirm that a PC demo would be coming “after release,” and that has proved to be the case.
You should be able to pick up the demo right now through the Windows 10 store (Forza Horizon 3 is Windows 10 only). It will presumably contain the same events and free roam capacities as the Xbox One demo released earlier in the year.
If that’s the case, expect to be able to do the following: “Blast along ocean-side roads, and race on the beach alongside the famed Twelve Apostles landmarks … grab ludicrous air off of danger sign jumps buried deep in the Australian rainforests, and have a chance to get sideways through Drift Zones in Byron Bay. Once you’ve finished all the events in the demo, you’ll be able to hop online and join your fellow Forza friends in an online free-roam session to explore the demo’s map together.”
