Microsoft has announced the first set of Game Pass additions for September 2025, featuring the highly anticipated Hollow Knight: Silksong. After a seven-year wait, the sequel to the indie hit Hollow Knight will be available on the Ultimate and PC versions of Game Pass on September 4, with a $20 price tag across all platforms. Additionally, the fast-paced shooter I Am Your Beast from Strange Scaffold will be added to the Ultimate, PC, and Standard Game Pass on the same day. Another Metroidvania, Nine Sols from Devotion developer Red Candle Games, will join the Standard Game Pass lineup on September 3, after being available on the Ultimate and PC versions since last November. The article also mentions other upcoming Game Pass additions, including the real-time strategy game Cataclismo, the 3D action adventure Paw Patrol World, and the disaster recovery/construction sim RoadCraft. However, it notes that several games, including All You Need is Help, Wargroove 2, and We Love Katamari Reroll+ Royal Reverie, will be leaving the Game Pass library on September 15.
