Microsoft has announced two pre-order bonuses for Halo: Combat Evolved Anniversary.

If you pre-order at selected retailers you will receive;

Master Chief Avatar Armour- Heroes never die, and to honour the 10th Anniversary of John 117, you will finally be able to transform your Xbox LIVE Avatar into the iconic hero by outfitting it with Master Chief’s signature MJOLNIR Powered Assault Armour.

“Grunt Funeral” Skull- An exclusive, game-modifying skull that changes the rules of the game for an explosively humorous experience, “Grunt Funeral” sends “Halo’s” most lowly and lovable enemy out in a blaze of glory. And plasma. And then more glory. Once the skull has been activated, every grunt’s methane tank will explode like a plasma grenade when killed. Watch out for the grunt chain reaction!
