Images of the retail copy of Halo 4 (two Xbox 360 discs) have been leaked and been posted on both NeoGAF and Reddit, with users posting images of their accounts with Halo 4 in their history.
If a retail copy of Halo 4 is out in the wild, it’s likely just a matter of time before the game is pirated online.
However, Microsoft will likely be banning anyone caught playing unauthorized versions of the game.
