Microsoft's Xbox Game Pass service has been on a role, and it seems like the hits will just keep on coming. Microsoft has announced a whopping 13 new games that will be coming to Xbox Game Pass over the next couple of weeks, including some day one Xbox Game Pass titles that weren't confirmed until just now. Needless to say, Xbox Game Pass subscribers should have plenty to keep them busy between now and the end of the month.

Things will get started on September 15 when day one Xbox Game Pass game Flynn: Son of Crimson hits the service on PC, console, and cloud. Then on September 16, I Am Fish, Skatebird, and Superliminal will also be joining Xbox Game Pass across PC, console, and cloud. Stealth action game Aragami 2 is yet another day one Xbox Game Pass title coming this week, hitting the service on Friday, September 17.

Then on September 23, Xbox Game Pass subscribers can look forward to four more new games in the form of Lost Words: Beyond the Page, open world indie game Sable, Subnautica: Below Zero, and Tainted Grail: Conquest. All of these games will be joining Xbox Game Pass across PC, console, and cloud, with the exception of Tainted Grail: Conquest, which will be exclusive to the PC version of the Xbox Game Pass service.

On September 28, FPS fans can look forward to turn-based first-person shooter Lemnis Gate joining Xbox Game Pass on console and PC, while RPG enthusiasts may be happy about classic-style JRPG Astria Ascending joining the lineup on September 30 across PC, console, and cloud. Finally, Xbox Game Pass will end its new games for September 2021 with the release of Unsighted on PC and console.

Microsoft has also confirmed an Xbox Game Pass game that's joining the service on October 1. As it turns out, strategy game Phoenix Point will be making its console debut as a day one Xbox Game Pass game. Phoenix Point is similar to the XCOM franchise, but swaps the alien invasion concept for more of a horror vibe with Lovecraftian creatures. It received somewhat mixed reviews at the time of its initial PC release, but perhaps it can get a second lease on life when it comes to consoles.

Of course, there will be other games coming to Xbox Game Pass in October as well, with the highest profile one being Back 4 Blood, the Left 4 Dead spiritual successor that will join Game Pass as a day one release on October 12.
