This Weekend on Game Pass: 3 Must-Play Games to Slay Your Backlog (Sept. 13-14)

The Xbox Game Pass library is a constantly evolving beast, with new titles dropping and old ones leaving every week. This weekend, September 13-14, 2025, is no different, with a fresh wave of games making their debut and others leaving for good. From a highly-anticipated indie masterpiece to a massive AAA blockbuster, the September lineup offers something for everyone. If you’re looking to dive into something new or finally tackle that ever-growing backlog, here are three essential Game Pass games you should be playing this weekend.

1. Hollow Knight: Silksong

After what feels like an eternity of anticipation, Hollow Knight: Silksong finally arrived on Game Pass on September 4, and it is every bit the masterpiece fans have been waiting for. This sequel to the beloved Metroidvania places you in the role of Hornet, the princess-protector of Hallownest, as she ascends to a vast new kingdom. The game expands on everything that made the original great, from its gorgeous hand-drawn art style and challenging combat to its mysterious lore and sprawling world design. Silksong is a game that demands your attention, with every new area revealing a stunning secret and every enemy encounter requiring a mastery of its deep combat system. If you haven’t already, clear your weekend and get lost in the beautiful, haunting world of Pharloom. The game’s incredible review scores and high search volume make it a must-play for any Game Pass subscriber.

2. Borderlands 4

For those who prefer a more chaotic and explosive weekend, look no further than Borderlands 4. The latest installment in the iconic looter-shooter franchise, which hit Game Pass on day one on September 12, takes Vault Hunters to the new planet of Kairos. With billions of guns, a cast of new, hilarious characters, and a massive open world to explore, Borderlands 4 is a pure dose of adrenaline-fueled fun. The game has been lauded for its fluid new movement mechanics, creative enemy design, and its signature brand of absurd humor. Whether you’re a long-time fan or a newcomer to the series, this is the perfect time to grab your friends, grab a gun, and start shooting. The game’s sheer content volume and highly replayable loop mean you could spend the entire weekend on this one title alone and not even scratch the surface.

3. I Am Your Beast

Looking for a quick, brutal, and satisfying thrill? Then you should be playing I Am Your Beast. This short but sweet first-person shooter arrived on Game Pass on September 2 and has been a sleeper hit. The game puts you in the boots of a lone operative who has to escape a relentless military-industrial complex in the North American wilderness. The gameplay is a fast-paced, high-stakes affair that’s all about speed and strategy. You’ll need to use your wits, the environment, and your enemies’ own gear against them to survive. It’s a game that’s perfect for a quick session, a palate cleanser between larger titles, and a great way to scratch that high-octane action itch. It’s a hidden gem in the Game Pass library that deserves to be played and is a great example of the kind of creative indie titles that make the service so valuable.

With three massive games to choose from, your weekend is officially booked. Whether you’re soaring through the skies of Pharloom, blasting your way through Kairos, or escaping the wilderness, Game Pass has you covered. Enjoy the gaming!
