Why voyages stay with players

See the impossible. Live with the answer.

Stellar Broadcast combines systemic survival with encounters that move, stories that return, and a civilization you can carry beyond the final screen.

Actual animated gameplay

Our pride and joy

Encounters that move around your decision

Black-hole lensing, living nebulae, stellar eruptions, impossible machines, temporal distortions, and alien interfaces are built as responsive scenes—not decorative backgrounds.

Fan-favorite chain stories

The voyage remembers

Some stories unfold across several jumps, with later chapters determined by the priorities you established earlier.

Share what survived

Your colony is more than a score

Export the complete colony report—or share an individual discovery from the Voyage Log—so the world, voyage, and civilization all remain part of the story.

Your voyage awaits

Scan alien worlds. Make impossible choices. Shape humanity's future.

Explore every system in detail

Ship management, puzzles, worlds, Legacy progression, daily voyages, and more.

Procedural Worlds

Every voyage is unique. Discover planets with distinct atmospheres, gravity, resources, biodiversity, and hidden anomalies.

289 Events

Asteroid fields, alien signals, crew conflicts, derelict armadas, alien trader encounters, and 23 production visual event treatments. Every encounter has branching outcomes with real consequences.

15 Ship Systems

7 core systems, shields, landing gear, plus 6 scanner subsystems. Hull, cryopods, navigation, Society, Culture, technology, constructors, and more shape whether the voyage survives.

Legacy System

Points carry between runs. Unlock permanent upgrades: reinforced hulls, advanced scanners, warp navigation, and more.

Deep Scanning

Survey probes verify all six scanner readings and can reveal hidden surface features before you commit. Explore 53 feature types and consider habitable moons as alternative landing sites.

Multiple Endings

From a Golden Age to desperate survival colonies to extinction. Your ship's condition and the planet's traits shape the epilogue across multiple ending tiers.

Event Chain Narratives

Multi-event story arcs that unfold across the voyage — early choices echo into later encounters, building a narrative unique to each run.

Governance Ideology

Five ideological axes shaped by your decisions throughout the voyage. The colony you found reflects the culture you built in transit.

Resource Sink Economy

Spend fuel, energy, and probes to tilt the odds in high-stakes encounters. Every resource has a value — spend it wisely or hoard it to the end.

Look under the hood

A narrative colony ship roguelike with systems deep enough to surprise you every run: procedural generation, puzzles, visual encounters, audio, logs, and online challenges.

Planet Names with Character

Planet names are generated locally to give each world an identity. Compatible mobile builds can use an optional on-device neural model; other builds use deterministic authored naming rules. No cloud connection is needed.

Local Generation Optional Mobile Neural Model Offline Naming

Alien Puzzles

Not just text choices. Decode crystalline transmissions, identify spectral signatures, and map constellations across seven procedurally generated puzzle systems. Patterns and challenges vary between encounters.

Billions of Worlds

Planets have 5 moon types, 6 ring types, 53 surface features, native civilizations, and government types — all procedurally composed. Habitable moons offer alternative landing sites. Surface conditions cluster around realistic ranges with rare extremes that keep you guessing.

Original Soundtrack

Ambient music and custom sound effects react to game state. Critical alarms when systems fail, peaceful ambience scanning a garden world, the hum of warp engines between stars.

Seed Codes & Voyage Logs

Every voyage is logged with full stats: planets scanned, damage taken, colony details. Share seed codes to challenge friends on the exact same galaxy.

Cinematic Encounters

Twenty-three production visual event treatments combine fifteen dedicated encounter routes with eight enhanced event scenes. Navigate a black hole's gravity well, unravel a chrono vortex, explore a Dyson sphere, drift through a living nebula, decode a mirror array, discover an ancient seed vault, awaken a world engine, and confront hazards rendered beyond ordinary text choices.
