Stellar Broadcast

Stellar Broadcast is a science-fiction game about guiding humanity’s last survivors through an unknown galaxy. You play as the artificial intelligence aboard their colony ship, keeping the crew alive, investigating strange signals and searching for a world where civilization can begin again. Each voyage generates a different chain of planets, discoveries, dangers and decisions.

The voyage

You manage the ship’s systems and supplies while responding to events that can have lasting consequences. These include equipment failures, dwindling resources, crew disagreements, scientific discoveries, alien encounters and other crises that may determine whether humanity reaches its destination intact. What you sacrifice along the way can matter as much as what survives.

You must manage:

• Hull, shields, navigation, cryopods and landing systems
• Fuel, energy, water, probes and surviving colonists
• Technology and scientific capability
• Crew society, morale and cultural identity
• Relations with the civilizations you encounter

Read the signals

Scientific and communication puzzles draw on astronomy, mathematics and the search for extraterrestrial intelligence. You analyze spectral lines, interpret alien number systems, reconstruct transmissions and distinguish meaningful signals from the noise of deep space. Solving puzzles can reveal valuable knowledge or open a conversation with something waiting in the dark.

Explore new worlds

Procedurally generated planets vary in atmosphere, oceans, climate, moons, rings, surface formations and signs of civilization. Their features offer clues about what lies below, though scanner readings can be incomplete. You decide whether to spend a probe to learn more, risk landing or continue deeper into space.

Worlds may have vast oceans, volcanic regions, electrical storms, crystal caverns, floating islands, ancient ruins, ghost cities, orbital debris fields, alien monuments and other phenomena. Their appearance reflects their nature, rewarding attention to visual evidence as well as instrument readings.

Shape a new colony

Landing is only the start. The chosen world, the ship’s condition, the people you save, the technology you preserve and the relationships you form all influence the colony that follows. The game records the development of its government, society, culture, technology, construction and relationship with native life. A seemingly hospitable world can destroy an unprepared colony, while preparation, technology and sacrifice may help overcome a hostile one.

Voyages and legacy

No two expeditions follow exactly the same path. You earn Legacy Points, unlock permanent improvements, try different strategies, revisit past voyages in the log and share generated seeds with other players. Voyages can lead to multiple outcomes, and the game also includes long-term progression, seeded challenges, voyage records, Steam Achievements and leaderboards.
