Xbox players are getting one of the most packed early‑December weeks in a long time, with more than 30 games landing on Xbox Series X|S, Xbox One, and PC between December 1 and 5.​ Headliners include Marvel Cosmic Invasion, the retro‑inspired Marvel beat ’em up launching straight into Game Pass, and Octopath Traveler 0, the next HD‑2D RPG from Square Enix.​ The lineup is filled out with horror experiments, family‑friendly platformers, and a surprising number of puzzle and sim titles, so there’s genuinely something for every kind of player.​

Below is a breakdown of the week by day so you can decide what deserves a spot on your Xbox or PC first.

December 1: Marvel Cosmic Invasion, crime, and the end of humanity

December kicks off with a bang thanks to Marvel Cosmic Invasion, backed up by new indie and simulator releases on Series X|S.​

• Marvel Cosmic Invasion (Game Pass, Series X|S, PC, Xbox Play Anywhere)
  Tribute Games and Dotemu are back in the beat ’em up lane, this time teaming with Marvel Games on an original side‑scrolling brawler that plays like a love letter to both arcade classics and the Marvel Universe. Expect tight combo‑driven combat, dazzling pixel art, and a roster of iconic heroes as you planet‑hop through a cosmic threat either solo or in drop‑in/drop‑out co‑op, locally or online. The big win for subscribers is that it launches day one into Xbox Game Pass, with support for handheld‑style play and Xbox Play Anywhere.​

• Crime Simulator (Series X|S)
  If you prefer breaking the law to enforcing it, Crime Simulator casts you as an ex‑con trying to pay off a lingering debt by sneaking into houses, cracking safes, and outsmarting security systems. Jobs can be tackled solo or in four‑player co‑op, and you’ll use everything from lockpicks and sleeping gas to brute force as you race the clock to make enough money before everything comes crashing down.​

• Seven Days Until Morning (Series X|S)
  This atmospheric survival game jumps seven centuries into the future as humanity collapses and you flee to Pluto in a last‑ditch attempt to outlive the disaster. You’ll manage life inside a centuries‑old emergency bunker, maintain the failing systems, and try to outlast at least the first week of the Plutonian night while something outside stalks the end of the human race.​

December 2: Brawls, bonfires, bundles, and nightmares

Tuesday brings a wildly varied mix: arena brawling, cozy puzzles, a winter value pack, family platforming, and a new horror experience.​

• Brok: The Bar Brawl (Xbox, PC, Xbox Play Anywhere)
  A spin‑off of the BROK universe, this game drops former boxer‑turned‑detective Brok into an underground bar hidden in the Slums, where his old instincts kick in. Play solo or in co‑op through challenge “event match”‑style encounters that riff on platform fighters, meeting a cast of oddball patrons and uncovering surprises as the story unfolds.​

• Cute Bonfire (Series X|S)
  Cute Bonfire is a relaxed, cozy, tile‑based puzzle game where you guide a little fire spirit inside a fireplace, pushing charcoal pieces to light bonfires across 30 handcrafted stages. With its gentle difficulty curve, pixel‑art presentation, and low‑stress design, it looks tailor‑made for short, satisfying sessions and younger players.​

• Elon and Friends: Winter Pack – 13 Games (Series X|S, Xbox Play Anywhere, PC)
  This winter‑themed bundle is all about value: it packs in a collection of small arcade‑style games including Elon and the Divine Proof, Green Soldiers Heroes, Extreme Bikers, Prison of Illusion, Super Snake Block DX, and SHMUP Mania. On PC, these titles are tuned for handhelds, so if you have a portable Windows device alongside your console, this pack gives you a lot to tinker with.​

• Sleep Awake (Series X|S)
  Sleep Awake is a first‑person psychedelic horror narrative set in the last known city on Earth, where sleep equals disappearance thanks to a mysterious phenomenon called The Hush. Playing as Katja, you’ll navigate competing death cults, solve environmental puzzles, and desperately try to stay awake long enough to understand what’s happening before you’re swallowed by the same fate.​

• Slimeboo (Series X|S, Xbox Play Anywhere, Optimized for Handheld)
  Slimeboo is an ultra‑accessible one‑button platformer built with children in mind, starring Boo, a tiny slime lost on a tropical island. You time jumps to clear obstacles and guide Boo home, making this a simple, family‑friendly platformer that also works well on handheld devices.​

December 3: Big JRPG, horror mini‑experiences, and quirky adventures

Midweek brings some of the most interesting genre variety, from a major JRPG launch to retro‑inspired horror, roguelite quack‑tics, and emotional storytelling.​

• Octopath Traveler 0 / Octopath Traveler 0 Digital Deluxe Edition (Series X|S, Xbox Play Anywhere)
  The newest entry in the Octopath series returns to the world of Orsterra with a prequel‑style story centered on restoration, retribution, and the mysterious divine rings. You still get the signature HD‑2D look that mixes retro sprites with 3D environments, plus the familiar Path Actions and Break/Boost battle system, but now there’s character creation and town building so you can craft your own protagonist and rebuild a ruined hometown. The Digital Deluxe Edition layers in extra digital goodies for fans who want the full package.​

• Caput Mortum (Series X|S)
  Caput Mortum is a short but intense first‑person horror experience that draws heavily from old‑school dungeon crawlers and PS1‑era survival horror. You descend a tower stuffed with eldritch nightmares and obscure secrets, where each step could be lethal as you search for forbidden knowledge that probably should have stayed buried.​

• Dungeons and Ducklings (Xbox)
  Quack‑inspired roguelite Dungeons and Ducklings has you playing as Mama Duck, whose pond has been corrupted by a lich that also kidnapped her ducklings. The action plays like a “QuackMan” maze‑crawler: you’ll storm dungeons, smash through walls and enemies with an attack button twist on classic arcade controls, and rescue ducklings on your way to the lich showdown.​

• Malachite: Temple of the Sun (Xbox)
  Malachite: Temple of the Sun is a match‑3 puzzle game set inside a forgotten jungle temple where every victory helps you construct and customize the temple itself. Players can switch between a structured adventure mode and an endless mode, using power‑ups and color‑matching skills to keep runs going as long as possible.​

  In Octo Curse, a pirate captain is transformed into an octopus by an evil spirit and must climb a mysterious tower to save the crew and reverse the curse.

• RoboHero (Series X|S)
  RoboHero reshapes classic sokoban puzzle design with a sci‑fi twist, sending an AI‑driven expedition robot to the exoplanet Xeran in search of precious resources. You’ll push and position objects through increasingly complex levels, using limited moves and spatial reasoning to solve logistics problems on an alien world.​

• Winterlight – Where Silence Says It All (Series X|S, Smart Delivery)
  Winterlight is a narrative adventure focused on quiet conversations and emotional choices, following Elias as he returns to a coastal hometown he once escaped. Much of the game unfolds through small moments—talks with townsfolk, bookstore chats over coffee, and reflective decisions that shape this “bittersweet homecoming” over a slow winter.​

• Yakuza: Shadows of New York (Series X|S, Xbox Play Anywhere, Smart Delivery)
  Yakuza: Shadows of New York shifts the usual Japanese underworld vibe to a gritty New York setting where enforcer Kaito Nakamura hunts for a missing mentor. You’ll fight through the city’s criminal underbelly while navigating clashes between old‑school honor codes and modern corruption in a story‑driven action adventure.​

December 4: Horror, shooters, sims, and story‑heavy indies

Thursday might be the single densest day of the week, with horror games, experimental narrative titles, and a few more unusual releases.​

  Blood: Refreshed Supply brings back the cult‑classic 90s shooter with modern enhancements, following undead gunslinger Caleb on a revenge quest against his former dark god, Tchernobog.

• Routine (Game Pass, Series X|S, PC, Optimized for Handheld, Smart Delivery)
  Routine is a first‑person sci‑fi horror set on an abandoned lunar base built around an 80s vision of the future, all CRT aesthetics and analog tech. What starts as curious exploration quickly becomes a stealth‑driven survival scenario as you realize the base’s systems—and something hunting you—consider you the real threat. Routine launches directly into Game Pass on console, PC, and cloud, with full next‑gen optimization.​

• Baseless (Series X|S)
  Baseless is a challenging planet‑hopping shooter where every planetoid has its own 360‑degree gravity, forcing you to constantly re‑orient while fighting enemies. With powerful weapons, rescue targets, and a galaxy to liberate, it looks like a good fit for players who enjoy fast arcade shooters with a mechanical twist.​

• Detective – Rainy Night (Series X|S, Xbox Play Anywhere)
  Detective – Rainy Night is a mystery horror game about Iker Carmona, a police officer investigating disappearances who stops at a small roadside motel called the Holiday. What seems like a routine overnight stay turns into a tense, narrative‑driven investigation as the motel reveals increasingly sinister secrets.​

• Finding America: The Heartland Collector’s Edition (Xbox)
  This hidden‑object adventure doubles as a U.S. road trip, sending you across the American Heartland, from Mount Rushmore and national parks to jazz bars and Midwest farms. Each chapter features hidden‑object scenes, minigames, and unlockable trivia, leaning into a laid‑back “travelogue game” vibe.​

• Mist: Evolution (Series X|S)

• ReSetna (Xbox)
  ReSetna casts you as a warrior in a post‑human world where the last remnants of humanity exist as minds trapped in circuits. Across seven hostile zones and seven boss fights, you push through an upgrade system, uncover a dark truth about what’s left of civilization, and ultimately decide whether this future is worth saving.​

• Sacrifice For Sale (Series X|S)
  This narrative experiment puts you in a hostage situation led by a cult, but the twist is that you respond directly to characters in more conversational, reactive ways. The goal is to learn about your captors, manipulate their beliefs, and deconstruct the cult hierarchy to avoid becoming the next sacrifice.​

• Sophia’s Animal Clinic – Mission Wildlife Park (Series X|S, Smart Delivery)
  Aimed at younger players and animal fans, this sim lets you manage veterinary work inside a wildlife park, treating horses, deer, ducks, goats, rabbits, and more.

  The latest in the viral spot‑the‑difference horror series has you watching security cameras for anomalies that range from subtle environmental shifts to disturbing intruders.

  Santa’s World is a Christmas‑themed jump‑and‑run platformer built around finding three lost gifts per level while dealing with traps, enemies, and environmental hazards. You can pick up snowballs to eliminate foes, and the 2.5D presentation is designed to evoke classic platformers with a festive twist.​

  Set in 1996, Security Booth: Director’s Cut puts you in a guard booth at a lab called Nova Nexus on a night when something very wrong is happening inside.
