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.

Creepy Jar is ready to turn up the heat as the studio’s sophomore effort, StarRupture, is available now on Steam Early Access at a special Early Access launch price of $15.99 (20% launch discount) before it goes to its regular price of $19.99.

Playing solo or with up to 4 players together, StarRupture’s Early Access release is the culmination of Creepy Jar’s well-earned experience alongside crucial feedback from their dedicated fans, and there’s so much more to come in the journey to 1.0.

“The current stage of our game already allows for world exploration, gathering resources, building machines that mine, harvest, create and assemble. All of this, along with combat mechanics and survival elements can be played both in single-player mode and in up-to-4-player online co-op.”

“In StarRupture in Early Access we intend to offer the majority of gameplay mechanics we’re planning for the full release to be polished and ready to enjoy. This will include an up-to-4-player co-operation mode in which you will be able to build, fight and explore a vast part of our rich open world. The full release is planned to contain more biomes, enemies, buildings and mechanics, along with a compelling end game. In Early Access we plan on constantly adding new content and enriching the gameplay along with close cooperation with our Community.”

Keeping that in mind, alongside today’s launch, the Creepy Jar team is also sharing the game’s very first roadmap so players can get an idea of what’s heading their way over the next few months and beyond, including:
