If you have an Xbox Live Gold subscription, time is running out to download two of the Games With Gold for August 2018. As usual, Microsoft's freebies are available during staggered windows throughout each month. Come August 31, you'll no longer be able to download Forza Horizon 2 and Disney Epic Mickey 2: The Power of Two for free. To grab your games, either visit Microsoft's Games With Gold page online or from your Xbox One's home screen.

Forza Horizon 2 is one of the Xbox One games available in August. It's an open-world racing game from 2014 that's set in Southern France and Northern Italy. It has the Forza series' realistic-feeling cars, but also offers many features typically found in arcade-style racing games (like a set of races that pit your car against an airplane). This game is going to be delisted from the Microsoft Store soon, so this is one of your last chances to grab it.
