Rakuten has some crazy sales for Xbox One owners. New customers, or simply folks who make new accounts, can make use of the promo code TREAT4U to get some huge savings on Xbox One games. Call of Duty: Ghosts can be yours for only $6, while Battlefield 4 will set you back $16. Being able to get the two biggest FPS games of the past two years for around $20 is insane. If you’re not into shooting, Madden 25 is $10, and finally, Assassin’s Creed IV: Black Flag is $10. Realistically, you can’t go wrong with any of these games at those prices – so if you’ve got an Xbox One and don’t mind having a game at a slightly-inferior resolution to its PS4 equivalent, then be sure to snatch these deals up as soon as possible.
