I just have call of duty ghost and I installed the game into my hard drive.
I also downloaded the simon 'ghost' riley pre-order bonus but it doesn't appear in the 'customize character' menu in the game.
I searched all menu's but nothing and now my code is wasted.
My hard drive shows under CoD ghost:
