There are quite a few gaming subscription services out there, but one that provides some of the best value is undeniably Xbox Game Pass. Microsoft has worked to make Xbox Game Pass a must-have for Xbox gamers, loading up the service with over 100 games and many other bonuses. Now it seems Microsoft is going to make Xbox Game Pass an even more appealing prospect, as it has teased the return of a popular game that was previously removed.

The official Xbox Game Pass Twitter account posted a fake email written by "Melissa McGamepass," designed to look like an email to the Game Pass team. It includes teases about what fans can expect from Xbox Game Pass in early 2021, which will apparently include the return of a popular game that was previously removed from the service. What the game is and when it will be coming back to Xbox Game Pass is unclear, but more information should come sooner rather than later, as it's expected to happen at some point later this month.

The mystery game's identity has not been revealed by Xbox, but there are some running theories, with fans zeroing in on three of the most likely possibilities. One, it's possible that the mysterious Xbox Game Pass game coming back in January 2021 is Grand Theft Auto 5 or Red Dead Redemption 2, as both games were massive additions to the Xbox Game Pass library. Another likely possibility is Fallout 4, which seems to make the most sense when one considers Microsoft's upcoming acquisition of Bethesda.

Meanwhile, the "email" also touches on some of the other Xbox Game Pass plans for January 2021. It opens with a statement about Bloober Team's The Medium, an upcoming survival-horror game that's being developed as an Xbox Series X console exclusive. Like other Xbox console exclusive games, The Medium will be available to play through Game Pass as soon as it launches on January 28. It's one of the first Xbox Series X console exclusives to date, so it will be interesting to see how it's received by fans.

And finally, the email also hints that the Xbox Game Pass cloud library will be growing in January 2021. Specific titles weren't mentioned, but more details should some soon. The way the email is written, it seems to be focused entirely on January 2021 content for Xbox Game Pass, so fans should expect announcements within the coming days.

But while Microsoft is looking to bolster Xbox Game Pass with new games and returning favorites in January 2021, it's worth pointing out that other titles will be making their departure. Mortal Kombat X has already left Xbox Game Pass, with Tekken 7 on its way out as well.
