The guys over at Xbox 360 Rally have done a fantastic job and gone to all the effort of writing up a Complete List of FREE Xbox 360 Live Marketplace Downloads..
Kudo's must go to the guys for putting in such a great effort..
Please remember that this is a US-based list! If you live in, say, Canada or the EU and see items on here that are region specific.
The Xbox LIVE Marketplace is a true cornucopia of stuff. Whether it be classic arcade games like Paperboy, Time Pilot and Contra, or downloadable content for your favorite games, like Santa Claus outfits for Saints Row and expansions for Oblivion, Xbox LIVE is chock full o’ stuff for just about everyone. If you have the MS Points, you can open the door to all the world’s delight and joy.
But what if you’re broke? Are you just left outside in the snow, to stare in the window from behind the bushes to see all the joyous boys and girls playing with their horse armor and their extra Crackdown skins? Of course not! There’s stuff for you, too, cheap ass!
In fact, there is a LOT of free stuff for you. Whether it be extra content for your favorite game, or the most worthless of things (*coughgamerpicscough*), there is a surprisingly large amount of free stuff for your downloading delight on Xbox LIVE.
