Resident Evil 4 HD download code Xbla for trade for another game download code

I recently bought the Resident Evil anthology for xbox 360, it came with download codes for Resident evil code veronica, Resident evil 5 gold and Resident Evil 4 hd...I already have Resident Evil 4 HD downloaded, looking to trade this code for another full game download code for xbox 360, interested in any genre...thanks! I am willing to trade it for a Halo Reach full game download code for 360 as well...
