Update (Tue 19th Sep, 2023): We've now got confirmation on which of these games will be leaving the cloud in late September as well, which we've added to the table below. Another thing to note is that Shenzhen I/O will seemingly no longer be leaving PC Game Pass on September 30th - so that's a bonus! Again, we've updated the table to remove this.
Original story (Sun 17th Sep, 2023): Microsoft has today revealed the second batch of eight games leaving Xbox Game Pass in September 2023, which includes some great titles such as Moonscars and Prodeus, as well as the Square Enix action-RPG, Outriders!
