Here's the deal for Xbox One gamers… Earthlock: Festival of Magic will be available to download free during the entire month of September. Assassin's Creed Chronicles: China will be available specifically from September 16th to October 15th.
For those still stuck with only an Xbox 360 (or an XB1 since these titles are backwards compatible)… Forza Horizon will be free to download from September 1st through the 15th, and Mirror's Edge will take over from the 16th through the end of the month.
See the video preview for September 2016 below.
