For those of you who own PS3 and plan on purchasing a PS4 soon, you are entitled to a $9.99 select rate on a few games from Activision, Ubisoft, and EA. The cross platform titles, Battlefield 4, Watch_Dogs, Call of Duty: Ghosts, and Assassin’s Creed IV: Black Flag are committed to Sony’s upgrade program via their respective publishers to save you money and get you gaming ahead of time. Purchasing a title like Call of Duty: Ghosts on PS3, for example, then repurchasing it on PS4 isn’t economically enticing; utilizing a pre-packaged code and your PS3 disk as an activating key you will be able to download a digital copy of the game on PS4 only for $9.99.
You’ll need to redeem your code and make the purchase before January 31st, 2014 (for Assassin’s Creed IV and Watch_Dogs), March 28th (for Battlefield 4), or March 31st (for Call of Duty: Ghosts) to receive this discounted rate. A PS4 is not required to redeem this key, it can be redeemed on the PlayStation Store prior.
