Surprise! Forza Horizon 4 is available to play right now on PC courtesy of a new that’s just been released.

The demo for Playground Games’ Forza Horizon 4 is available for both Xbox One and PC, and is available to download for free through the Windows Store. Sadly, that means it is Windows 10 only.

Forza Horizon 4’s demo weighs in at 27.83GB, making it one of the largest demo downloads in existence. It should provide a nice taster of what to expect from the open-world racer set in Britain ahead of its launch on October 2nd.

It's not clear at the moment just what's included in the demo but rest assured we'll be putting Forza Horizon 4 through its paces in a series of benchmark tests tomorrow. In the meantime, be sure to check out the official Forza Horizon 4 PC system requirements to ensure your rig's up to the lofty task of running the game.
