The box artwork shows Master Chief in his new armour design surrounded by alien ruins with an ominous ship in the sky overhead.
The game's cover design was put together by fans who were sent random pieces of the image by Microsoft. Fans congregated on the Halo Waypoint forums where they assembled the full image in under an hour.
Microsoft has since confirmed that the picture is the official cover art for Halo 4.
Set four years after the events of Halo 3, the sequel marks the return of iconic hero Master Chief and represents the beginning of a brand new saga.
Halo 4 will release exclusively on Xbox 360 on November 6 worldwide.
