Been sitting on a code for a Corbulo Emblem for Halo 4 for a good bit... Thinking someone else might get more use out of it, so I'm gonna offer it here.
Any hardcore Halo 4 folk interested? These are getting pretty hard to find. Regularly going on Ebay for $8-$20
I'd consider steam trades, Steam Wallet Funds, XB DLC, XB Points, Paypal or provocative images of your 5'9 blonde sister.
If you are interested, shoot me a PM with some offers and we'll see what we can work out.
