I was just over at Xbox360Fanboy, and they made me really excited. It looks like Electronic Gaming Monthly has a new Halo rumor on page 67 which states:
In last issue’s Rumor Mill, I mentioned that Xbox 360 owners will soon be able to buy full Xbox 1 games via Microsoft’s Xbox Live Marketplace. And now I’ve got the juicy scoop on the first game that Bill Gates’ crew will make available. Look for Bungie’s epic first-person shooter Halo on the Marketplace sometime before this summer. I only hope the developer makes this version’s multiplayer mode Xbox Live compatible.
I really hope they release Halo on the Marketplace. How many points would you pay to download the title? I think somewhere around 1200 to 1600 points would be good for such an old title, especially if it allowed four local players and multiplayer over Live.
