The next instalment in Turn 10's racing series, Forza Motorsport 6, is due in a month. The game is releasing exclusively on Xbox One on September 15, but already we have the list of achievements after it was dropped on the game's official website. Keep in mind that such lists often contain possible spoilers, although it might not be the biggest concern when it comes to a racer such as this. The list of achievements also reveals some previously unannounced cars. Check out Forzamotorsport.net to see the 57 achievements and the unannounced cars.
