Microsoft has outlined the dates and prices for its upcoming Summer of Arcade. This year's line-up, which as we've noted only includes one exclusive, will begin in August.
According to a post on the Major Nelson blog, Brothers: A Tale of Two Sons comes first on August 7 for $15 (1200 MSP). That's followed by Charlie Murder on August 14 for $10 (800 MSP), Flashback on August 21 for $10, and finally, TMNT: Out of the Shadows on August 28 for $15. Charlie Murder is the one exclusive.
Buying any two of the included games will net you a "Souls Pack" for Ascend: Hand of Kul once it releases.
