Stellar Broadcast

Humanity did not build one ark. It broadcast seed ships across the stars.

Earth is gone. You are the AI guiding the last colony vessel still crossing the void. Keep its colonists alive, navigate a failing ship, and find a world where civilization can begin again.

Stellar Broadcast is a narrative sci-fi survival roguelike where every voyage creates a different story.

SCAN STRANGE NEW WORLDS

Explore procedurally generated planets and moons with distinct atmospheres, climates, resources, gravity, radiation, water, and ecosystems. Deploy probes to verify uncertain scanner readings before risking the colony.

Discover 53 surface features, including crystal caverns, floating islands, electrical storms, ancient ruins, ice tunnels, ghost cities, and alien megastructures. Dense rings, multiple moons, native civilizations, seasonal lighting, storms, and planetary rotation give each system its own visual identity.

MAKE IMPOSSIBLE CHOICES

Face 217+ branching narrative events involving alien signals, damaged cryopods, crew conflicts, derelict ships, strange life, and failing machinery. Every decision has a cost. Some choices carry weighted outcomes, and multi-event story arcs can follow you across an entire voyage.

KEEP THE SHIP ALIVE

Manage 15 interconnected ship systems, including Hull, Navigation, Cryopods, Society, Culture, Technology, Constructors, Shields, Landing Systems, and six specialized scanners.

Balance fuel, energy, water, probes, and colonist survival. Awake colonists consume supplies. Damaged cryopods endanger sleepers. Trade resources, repair critical systems, and decide how much risk the mission can survive.

ENCOUNTER THE UNKNOWN

Discover 15 bespoke animated encounters, from black holes and living nebulae to Dyson spheres, phantom ships, temporal vortices, ancient world engines, and impossible alien machines.

CHOOSE HUMANITY'S NEW HOME

Land on a planet or, when conditions allow, one of its moons. Your ship's condition, chosen world, discoveries, Society, Culture, and decisions all shape the colony that follows.

The final landing and colony reports reveal what thrived, what failed, and what your choices meant. Outcomes range from extinction and desperate survival to a Golden Age.

BUILD A LASTING LEGACY

Earn Legacy Points after every voyage and invest them in permanent, multi-rank upgrades. Improve ship systems, carry additional probes, strengthen scanners, study alien civilizations, or collect water from ice rings with a Bussard Collector.

Return to the Legacy Hub to review achievements, discovered worlds, voyage records, and the history of every colony you founded.
