Silksong leads Xbox Game Pass additions in September 2025

Microsoft has announced the additions to Xbox Game Pass in September 2025, which are being led by Team Cherry’s highly-anticipated Hollow Knight: Silksong. The action adventure game will be available on the service right from release for everyone with Ultimate or PC Game Pass.

Fans of strategy games can look forward to September 4 as well, since Cataclismo will come to the library alongside Silksong. The brick-based survival strategy game mashes together LEGO and Stronghold, tasking you with constructing a fortress that can survive the onslaught of entire armies of nightmarish creatures.

Altogether, September – at least when it comes to the first release wave – is not a massive month for Game Pass additions, though, with only four games joining the line-up.

Xbox Game Pass additions in September 2025

• Hollow Knight: Silksong (Cloud, Console, and PC) – September 4
• Cataclismo (PC) – September 4
• PAW Patrol World (Cloud, Console, and PC) – September 10
• RoadCraft (Cloud and Xbox Series X|S) – September 16

Additionally, Nine Sols is moving to Game Pass Standard on September 3 on Xbox Series X|S.
