“Read Dead Redemption” was made available for Xbox One but Microsoft was none too happy about it.

The popular Western game, currently available for Xbox 360 but not on the Xbox One, somehow became temporarily playable for the 2013 game console. Few days ago, the open world game can be accessed through what appears to be a “hack.”

However, employing such sly method is no longer effective ever since Microsoft discovered that Xbox Live users resorted to it. As a matter of fact, the tech giant issued a warning for anyone caught taking advantage of the glitch.

As posted in PCMag, Microsoft Xbox Support has this to tweet as a reply to a certain concerned gamer who asked about the shady technique:

“Hey there! This game isn’t available for back compat according to http://bit.ly/1UZtMAd . We suggest not doing what is shown in the video. Playing a game before it’s been authorized to play on the service is against the Code of Conduct. ^AK,” stated the support staff.

According to IGN, the exploit was due to an error which resulted from tests made on Xbox 360 games.

“Microsoft tests all Xbox 360 games with our emulator to ensure a quality experience across a breadth of titles,” Larry Hryb, director of programming for Xbox Live, posted on Reddit. “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.”

It appears that “Red Dead Redemption” is not the only game affected by this. The game, however, gained attention during the bug because it is one of the many Xbox 360 game most requested for Xbox One. It ranks third place below “Call of Duty: Black Ops II” and “Skyrim.”

Looks like the much-loved Western game, along with some other titles, are ready for the Xbox One. All that is needed is an official announcement from Microsoft.
