Xbox’s early December lineup brings a wide-ranging mix of action games, narrative adventures, platformers, puzzle titles, and horror experiences across Xbox Series X|S, Xbox One, PC, and Game Pass. The week of December 1–5, 2025, features several high-profile launches alongside a long list of indie releases, giving players a broad selection no matter their preferred genre. While all dates are subject to change, the schedule highlights Xbox’s continued momentum heading into the end of the year.
Major Franchise Expansions and High-Profile Releases
The week begins with the arrival of Marvel Cosmic Invasion on December 1. Tribute Games and Dotemu collaborate once again to deliver a new beat ’em up adventure that spans multiple planets in a pixel-art interpretation of the Marvel universe. The game supports local and online co-op, along with an adaptive drop-in/drop-out system designed to keep players engaged whether they’re solo or teaming up with others. Its Game Pass launch further positions it as one of the week’s standout releases.
On December 3, Square Enix brings Octopath Traveler 0 to Xbox, expanding the HD-2D role-playing series. The latest entry adds character creation and town-building to the classic Path Actions, Break and Boost mechanics, and retro-inspired presentation. The story centers on the divine rings and the world of Orsterra, continuing the franchise’s emphasis on branching roles and strategic turn-based combat.
Routine arrives on December 4 as one of the week’s major horror offerings. Set on an abandoned lunar base designed around an imagined 1980s future, Routine blends slow-burn exploration with high-tension survival. With Game Pass availability, Xbox Play Anywhere support, and handheld optimization, it aims to reach a wide audience across platforms.
Indie Highlights and Genre Variety Throughout the Week
Alongside the bigger releases, Xbox’s catalog expands with numerous indie titles that bring distinct mechanics and thematic variety. Crime Simulator launches on December 1, offering stealth heists, co-op play, and progression systems centered on repaying heavy debts through burglary. Seven Days Until Morning, also out the same day, presents a survival narrative on Pluto as players maintain a centuries-old bunker and confront the collapse of humanity.
December 2 includes a diverse batch of games such as Brok: The Bar Brawl, which blends narrative investigation and platform-fighter-inspired challenges, and Sleep Awake, a first-person horror experience set in a city gripped by insomnia and a mysterious phenomenon known as The Hush. Cute Bonfire and Slimeboo serve as light, family-friendly alternatives with straightforward puzzle and platforming designs.
On December 3, players will find another substantial group of releases, including Caput Mortum, a short first-person horror journey inspired by retro dungeon crawler design, and Winterlight – Where Silence Says it All, a narrative adventure focused on quiet decision-making, memory, and community in a winter coastal setting. Action-oriented players can look to Octo Curse, a platformer about a pirate transformed into an octopus, and RoboHero, a sokoban-style puzzle experience set on an exoplanet.
Yakuza: Shadows of New York also debuts on December 3, expanding the long-running franchise with a narrative set in New York’s criminal underground. The story follows enforcer Kaito Nakamura in his search for a missing mentor, blending personal stakes with organized crime conflicts.
Horror, Action, and Narrative Experiences Continue Into Week’s End
December 4 adds more horror-leaning releases such as Blood: Refreshed Supply, a modern update to the cult classic shooter featuring Caleb’s revenge quest against Tchernobog, and Mist: Evolution, a hybrid RPG built around real-time combat, idle elements, and a parent’s search for their missing daughter in a fog-covered world. Detective – Rainy Night also arrives, focusing on a police officer drawn into a sinister mystery at a roadside motel.
The Phantom lands on the same day, delivering an arcade beat ’em up adaptation of the classic comic character, complete with 14 levels, hand-illustrated cutscenes, and assistance from iconic animal companions. Additional titles like ReSetna, Sacrifice For Sale, and Sophie’s Animal Clinic expand the range of gameplay options with sci-fi action, interactive narrative design, and veterinary simulation.
Puzzle, Platforming, and Retro Action Close Out the Week
The final day of the release window, December 5, includes new horror, platformers, puzzle games, and retro-inspired titles. I’m on Observation Duty 8 continues the franchise’s focus on spotting anomalies through security cameras, maintaining its surveillance-driven horror format. Connect It offers a more relaxed challenge built around linking colors across a grid without overlapping paths.
Players seeking action can explore M.A.U.S, a mechanized defense adventure centered on Dr. Cavor’s attempt to protect Victoria, or Speed Factor, a retro racing game inspired by classic arcade driving. Family-friendly entries such as Pixapple Adventure, Santa’s World, and Stacky Dash round out the day, while Tank Mechanic Simulator – Reinforced delivers a detailed restoration and museum-building experience centered on World War II armored vehicles.
