Surely enough there were plenty of people that have already pre-ordered their copy of the 10th anniversary edition of Halo: Combat Evolved, and if you did that's great. If you didn't however, you should as its not the usual price for new games but also because its Halo.

Anyway the point is that if you were one of those that have pre-ordered your copy you can get some exclusive goodies. The bonus that you get is a XBL avatar revamped master chief mjolnir mark v armor, and a in game skull that will make grunts explode like a plasma grenade when they are killed (sounds like fun).
