Happy New Year! It's been a while since I have been on Gamespot's forums.
I was doing some cleaning up and found some Halo 4 bonus codes I never used.
I don't own the game on Xbox 360 anymore (I was planning to get XONE soon and the Halo collection)
I'm posting here because the Halo 4 forum isn't very active.
They are old - I can assure you I never used them, so I hope they work!
