Xbox Game Pass is adding eight titles in September, and upcoming Xbox Game Pass releases September now has a dated rollout instead of a vague monthly promise. RuneScape: Dragonwilds lands on September 15, while SpeedRunners 2: King of Speed arrives earlier in the month as a day-one release.
The schedule gives Game Pass Ultimate, Game Pass Premium, and PC Game Pass subscribers a clear order of arrival across Cloud, Console, Xbox Series X|S, Handheld, and PC. For players managing installs and subscription tiers, that timeline is the real news.
September 1 to 4
Shelldiver opens the month on September 1 for Game Pass Ultimate, Game Pass Premium, and PC Game Pass across Cloud, Console, and PC. SpeedRunners 2: King of Speed follows on September 3 for Game Pass Ultimate and PC Game Pass on Cloud, Xbox Series X|S, and PC, making it the month’s first day-one addition.
Dice a Million arrives on September 4 for Game Pass Premium, Game Pass Ultimate, and PC Game Pass across Cloud, Xbox Series X|S, Handheld, and PC. That early cluster matters because it front-loads three separate additions in four days, so subscribers do not have to wait until midmonth to see movement in the library.
Call of Duty and The Royal Writ
Call of Duty: Black Ops Cold War lands on September 8 for Game Pass Ultimate, Game Pass Premium, and PC Game Pass across Cloud, Console, and PC. The Royal Writ follows on September 10 for the same tiers across Cloud, Xbox Series X|S, Handheld, and PC, and Virtua Fighter 5 R.E.V.O. World Stage also joins on September 10 for Cloud, Xbox Series X|S, and PC.
Those two September 10 additions create the month’s only double drop, which gives subscribers a narrower decision window if they are planning around bandwidth, storage, or playtime. Xbox Game Pass in September is not spacing everything evenly; it is stacking releases where interest is likely to be highest.
RuneScape: Dragonwilds on September 15
RuneScape: Dragonwilds arrives on September 15 for Game Pass Ultimate, Game Pass Premium, and PC Game Pass across Cloud, Xbox Series X|S, and PC. The game is set in Ashenfall, and it is one of the month’s day-one additions alongside SpeedRunners 2: King of Speed.
TCG Card Shop Simulator also launches in 1.0 on Xbox on September 15, leaving Game Preview and moving into full-game release. That means the month closes with both a new arrival and a version change, so subscribers watching the calendar get two different kinds of release in the same slot.
The practical takeaway is simple: September’s first half already has a complete rollout plan, and the two day-one additions are the points to circle first. If you want the newest entries the moment they appear, September 3 and September 15 are the dates that matter most.
