Red Dead Redemption popped up as an Xbox One backwards compatible title over the weekend, allowing those who own the game to relive the story of John Marston in the old west. Its availability came to a surprise to Xbox One owners, even Microsoft.

Larry Hryb responded to a Reddit thread, which pointed out the availability of Red Dead Redemption to Xbox One owners.  According to Hryb, the availability of Red Dead Redemption and a handful of other titles was made in error. “"Microsoft tests all Xbox 360 games with our emulator to ensure a quality experience across a breadth of titles," he writes. "Due to an error some of the games currently in test were accidentally made available. We have since removed access to those games, and apologize for any confusion this may have caused. We will have more information on upcoming releases soon."

This weekend’s mishap included a number of games in addition to Red Dead Redemption, including Castlevania: Symphony of the Night, Alan Wake's American Nightmare, and Tekken Tag Tournament 2. As of this writing, access to those titles have since been removed.

Now that Microsoft is able to pull access to backwards compatible games that have accidentally been made available, it’ll now be a race to get these titles downloaded prior to the company removing them. So the next time we report on a game's accidental release, you should probably get it downloaded immediately.
