The medal, the Coalition equivalent of the Nobel Prize, is similar to an actual machine cog and each one features a unique code to unlock Adam Phoenix as a COG soldier for use in the multiplayer mode.
Priced at £59.99, the Limited Edition will feature the game in a special case, along with the Octus Service Medal awarded to Adam Phoenix, the father to main character Marcus Fenix, in recognition for inventing the Hammer of Dawn weapon. Microsoft has revealed details about the Limited and Epic editions for Gears of War 3.
