Unfortunately you’ll have to purchase Forza Motorsport 6 on the Xbox One to be able to drive them. Turn 10 Studios and the Forza team have partnered with Bethesda Game Studios to offer Fallout-themed cars as free DLC in Forza Motorsport 6. First on the menu is the blue and yellow 1956 Ford F100 seen in the video, available to current Forza 6 players today. Turn 10 also plans to offer the fictional Chryslus Rocket 69 from the Fallout universe sometime later in 2016. This free DLC will only be available to those who purchase Fallout 4 for Xbox One.
