StarRupture (previously known as Chimera) is an ambitious cross between base building, exploration, combat, and managing resources on an alien but oddly familiar terraformed planet torn by a catastrophic cycle of destruction caused by its titular star.

Being built in Unreal Engine 5, StarRupture is a story of man versus nature set against an otherworldly and breathtaking sci-fi environment where elemental cataclysms of extreme heat and cold loom as a constant danger. The player takes up the mantle as a convict exiled from the Earth to serve their sentence by mining and expanding industrial production alongside researching new technology on a seemingly hospitable new planet rife with mystery and danger. Tasked with surviving the waves of fiery inferno or extreme cold—not to mention facing down against hostile enemy monsters in tense combat—each cycle spells destruction yet ushers in a new era of growth and rebuilding. Whether solo or as part of an up-to-4-player co-op experience, players will explore, adapt, mine, gather resources, and build complex machinery in order to survive and prosper.

While StarRupture is a base builder by definition, in reality it is so much more. The game invites players to work together and push beyond their limits in their attempt to build, extract and process resources and survive. At the same time, they’re constantly facing the ticking clock of the Ruptura Star, which promises to eviscerate everything and everyone in its path. For fans of builders, management, sci-fi action, and combat StarRupture will challenge all comers to utilize the technology at their fingertips and weather both the extremities and fierce enemies in order to survive and create a prosperous industrial complex.

Explore the lush and beautiful landscape of a seemingly unassuming planet, but stay observant! In a relentless cycle of life, death, and rebirth it’s only a matter of time before Ruptura wipes the surface clean in a fiery rage as it has countless times before. Bear witness to the revival of the landscape as after every rupture, life springs forth anew with foliage shaking off the leftover ashes and reaching for the sky once more. Each cycle allows the player to explore new secrets or gather rare resources.

What other mysteries lie ahead? Exploration will reveal there is much more to this planet than meets the eye. Who walked these lands before you? What happened to them? Observe the remnants of previous expeditions and learn about their fate as you desperately try to survive in StarRupture.

The year is 2201 and your sentence begins now.

Originally planned for Fall 2025, Creepy Jar announced that StarRupture is coming to Steam Early Access on January 6, 2026. 

After an incredibly well-received two-week playtest, StarRupture has reached new heights—both in player enthusiasm and in Creepy Jar’s ambition for the game. As the playtest wrapped up, Creepy Jar announced StarRupture crossed over 500,000 wishlists with over 158,000 players jumping in to test their limits on the surface of Arcadia-7. Compiling nearly 200,000 hours watched on livestreams, the response has been nothing short of inspiring as the playtest earned a 91% positive review score and saw a peak of 6,701 concurrent players, making it clear that the community’s excitement is matched only by their overwhelming engagement and invaluable feedback.

“We're extremely pleased with the reception to the first open playtest of StarRupture. Our concept for this game is a unique blend of existing genres - base building, exploration, combat, and survival - and players clearly enjoyed it. We're thrilled that players noticed and appreciated this fresh take on the genre and mechanics they know and love.” - Krzysztof Kwiatek, the CEO of Creepy Jar.

The studio will take community feedback, refine every detail, and deliver the StarRupture experience their audience deserves. Originally expected to launch in the Autumn of this year, Creepy Jar is committed to delivering the best possible experience, and the player’s passion seen during the playtest has only fueled Creepy Jar’s drive to do more. The extra time means more polish, more improvements, and more reasons for players to fall in love with StarRupture when it launches on Steam early next year.
