Venturebeat.com reports that Rockstars epic adventures in the wild west, Red Dead Redemption, is playable on Xbox One - starting now! You can already download the digital copy but the physical disc is still not working. Probably a sign that this is something that will be announced upcoming week.
This is how Venturebeat says you should do to play Red Dead Redemption on Xbox One:
Go to the Find a Friend option in the Friends menu.
Search for "RockoHoward" — this is important.
Once you find that user, view his profile.
Tab over to his following list.
Sort by just "Games" not "Friends & games."
Find Red Dead Redemption.
Click on "See in store."
The "Install" prompt should appear for you.
