A while back I pre-ordered halo 4 from Mighty Ape.com hoping to be able to use the locus helmet which was promised as a pre-order bonus. Until recently I forgot about this bonus and upon realizing that i still have the code I attempt to redeem it. Unfortunately for me the moment that I hit done after typing in the code the xbox informed me that the code was invalid. At first I was optimistic thinking that I must have entered it wrong but after about 5 tries each confident that I had entered it correctly I had to give up knowing that I won't be able to access probably my favorite looking helmet in the game. At this point I'm wondering what to do and if anyone knows what I should do or knows how to help me please reply or pm me. Even if you're not able to help I appreciate those people who read taken their time to read this.
