Sumerian Six, Sunderfolk, and 2 More Games Are Free on Xbox This Weekend Through November 15
Right on the heels of Microsoft's 25th anniversary celebrations and Xbox Game Pass announcements, a fresh batch of weekend trials has arrived via Xbox Wire. Running from Thursday, November 12 through Sunday, November 15, 2026, at 11:59 PM PST, the latest Xbox Free Play Days lineup unlocks four full games for Xbox Game Pass Ultimate, Premium, and Essential subscribers on Xbox Series X|S and Xbox One.
This week's selection is headlined by two distinct strategy heavyweights: the real-time commando stealth thriller Sumerian Six and the phone-controlled couch co-op RPG Sunderfolk, joined by '90s internet detective sim Hypnospace Outlaw and procedural co-op shooter STUFFED.
Sumerian Six: Occult WWII Real-Time Tactical Stealth
Developed by Polish studio Artificer and published by Devolver Digital, Sumerian Six blends classic isometric real-time tactics with pulp alternate-history sci-fi. With Commandos: Origins - Deluxe Edition preparing its upcoming console rollout, this March 2026 Xbox Series X|S release puts players in command of the Enigma Squad, a covert unit of the world's brightest Allied scientists fighting behind enemy lines during World War II.
The squad's primary objective is to hunt down former colleague Hans Kammler, who is harvesting a mystical substance known as Geiststoff to build occult wunderwaffe and awaken ancient Sumerian demons for the Third Reich. Every scientist brings experimental powers to the field: chemist Rosa Reznick melts patrols with volatile concoctions, psychoanalyst Siegfried von Adelsberg bends enemy perception, siblings Sid and Isabella Sterling execute position swaps and optical cloaking, and Wojtek transforms into an armored werebear capable of tearing through mutated Nazi shock troops. Using the tactical planning mode, players can queue and synchronize multi-character takedowns to clear heavily guarded compounds in seconds.
Sunderfolk: Turn-Based Couch Co-Op Powered by Your Phone
For groups looking to gather around the living room TV, Sunderfolk,developed by Secret Door and published by Blizzard Entertainment co-founder Mike Morhaime's Dreamhaven label,reimagines the tabletop RPG night for up to four players. Instead of wrestling with complex rulebooks, plastic tokens, or forty-minute board setups, the game turns your smartphone or tablet into the controller.
By downloading the free Sunderfolk companion app on iOS or Android and scanning the on-screen QR code, each player manages their private hand of skill cards, equipment deck, inventory, and character sheet directly from their mobile screen while tactical turn-based combat unfolds on the main display. Players band together to defend the animal-folk village of Arden and its remnant of magical Brightstone against encroaching Shadowstone corruption across the Sunderlands. Seven asymmetric hero classes are available to master,Arcanist, Bard, Berserker, Pyromancer, Ranger, Rogue, and the Vanguard,with town-building upgrades and NPC relationships waiting back in Arden between dungeon expeditions.
Hypnospace Outlaw at 75% Off and STUFFED Round Out the Lineup
Alongside the two tactical headliners, Xbox Game Pass members can jump into two genre-blending indie titles all weekend:
- Hypnospace Outlaw (Tendershoot / No More Robots): Set in an alternate 1999 where users browse the web in their sleep via headband-mounted neural monitors, you play as a volunteer "Enforcer" patrolling weird personal homepages for copyright infringement, malicious viruses, and cyberbullying. Packed with garish animated GIFs, MIDI earworms, and hidden desktop secrets, the full game is also available at a steep 75% discount during the event, bringing its price down to just $4.99 (regularly $19.99 SRP).
- STUFFED (Waving Bear Studio / The Game Publisher): A first-person horde shooter playable solo or in up to four-player online co-op. Stepping into the stitched paws of a customizable teddy bear, you must guard young Ellie's bedroom door from waves of childhood nightmares,including rogue garden gnomes, giant rubber ducks, and creeping shadows,using popcorn cannons and jelly launchers across procedurally generated house layouts.

My Field Notes
Having Sumerian Six and Sunderfolk in the same free weekend rotation is a rare treat for tactics fans. Artificer's take on real-time stealth shines because of how cleanly its occult abilities interlock: chaining Isabella's position swap into Rosa's chemical dissolution and a synchronized Wojtek werebear mauling feels like solving a high-stakes clockwork puzzle. Meanwhile, I was just talking with Bastien "Orion" about how clearly Mike Morhaime's Dreamhaven DNA shows up in Sunderfolk's user experience. Offloading card hands and inventory management to a responsive phone app strips away all the physical friction of tabletop dungeon crawlers, letting four players focus purely on hex-grid positioning and turn order synergies. Carve out time for both before Sunday night's cutoff.
