Assassin's Creed IV Black Flag Freedom Cry
If you are looking for a good bargain and don't own assassin's creed black flags this is a great purchase for less than half of the full game and 4 to 5 hours of game play it is fantastic. For $14.99 you get a full game that is worth it and way longer than MGS Ground Zeroes!
My thought is if you are going to spend the fifteen bucks on this, just spend the five extra dollars and get the season pass. That's what i did.
