Big news for Xbox fans — December’s Game Pass lineup is packed with heavy-hitters, long-awaited revivals, and a few indie gems you might not expect. But here’s where it gets really interesting: some long-standing exclusives are finally opening up to more subscribers. Let’s dive in.
Leading the charge is none other than Mortal Kombat 1, launching December 10 for Ultimate and Premium subscribers. This legendary fighting series, which first made its mark in dimly lit 1990s arcades, has returned with a vengeance. The latest entry delivers an upgraded combat system, reimagined mechanics, and new playable modes — yet it proudly clings to its iconic identity. Expect the same brutal fatalities, splashy gore, and even those nostalgic, oddly charming transformations into tiny babies. The fun (and carnage) never really ends.
Then there’s Routine, a sci-fi horror project that’s been simmering for over a decade. That’s right — this atmospheric title was first teased back in 2012. Now, after years of speculation, it finally lands as a Game Pass day-one release for Ultimate subscribers. With its eerie retro-futuristic design and chilling tension, it promises to deliver dread in the best kind of way. Will it live up to the decade of hype? Or will it become another example of over-ambitious vaporware finally seeing daylight?
Up next is Dome Keeper, arriving December 9 for Premium and Ultimate members. This addictive roguelike blends mining and tower defense into a fast-paced experience that makes “just one more run” an actual threat to your sleep schedule. Its simple premise — dig, defend, and survive — hides a surprising amount of strategy, and it’s no wonder players keep coming back for another go.
Already available right now for Premium and Ultimate subscribers is Lost Records: Bloom & Rage, the narrative-driven adventure from the creators of Life is Strange. Set in the 1990s, it hums with nostalgic energy — think flannel shirts, mixtapes, and all the emotional storytelling magic that studio is known for. Players can expect a heartfelt journey packed with friendship, memory, and a dash of mystery.
And this is the part most people miss: several big-name titles that were once Ultimate exclusives are expanding to Premium as well. Some highlights include Indiana Jones and the Great Circle, Monster Train 2, 33 Immortals, and Spray Paint Simulator. If you’ve been waiting to try them without upgrading, this might be your perfect window.
So what do you think — does this month’s lineup live up to the hype? Are you here for the nostalgia of Mortal Kombat or the mysterious pull of Lost Records? Sound off in the comments — which December addition are you booting up first?
