I would have been happy with just Halo 2 Anniversary (undoubtedly the best game in the franchise) but with the addition of Halo's 1, 3 and 4 all updated for the Xbox One, plus the Halo 5 beta! How could you possibly turn down this amazing deal- This is a gift for all Halo fans!
In the words of Sgt Johnson: Hoo rah!!
