As announced on Tuesday (August 5, 2025) on Xbox Wire, Rain World (available on Cloud, Console, and PC) is now part of Game Pass Ultimate, PC Game Pass, and Game Pass Standard. It’s a charming indie adventure where you play as a nomadic slugcat—cuter than its scary name suggests.
A quartet of games will be available on Wednesday (August 6, 2025) to Game Pass Standard subscribers. According to IGN, these games include dice-based RPG Citizen Sleeper 2: Starward Vector and wintry downhill racer Lonely Mountains: Snow Riders, MechWarrior 5: Clans, and Orcs Must Die! Deathtrap, all for Xbox Series X/S.
Assassin’s Creed Mirage, the headline addition of August 2025, arrives for cloud, console, and PC for Game Pass Ultimate and PC Game Pass subscribers on August 7, 2025. This is the smaller, Baghdad-based installment starring street thief Basim, bringing the franchise back to its city roots.
Aliens: Fireteam Elite arrives on August 12, 2025, for cloud, console, and PC for all Game Pass members, including those on Ultimate, PC Game Pass, and Standard tiers. The game is coming out on the same day as the debut of the new series Alien: Earth, which launches on FX and Hulu. On August 14, a Game Preview build of the roguelike kingdom builder 9 Kings will launch on PC, available through PC Game Pass.
