Galactic Simulator 3

Fermi Paradox

“Where are they?”

To date, we have found no reliable evidence that extraterrestrial civilizations have visited Earth. With countless stars and planets throughout the galaxy, why does intelligent life appear to be so rare?

Humanity has survived its own journey through the Great Filter and become an interstellar civilization. Now it is time to leave the Solar System and search for civilizations that may—or may not—have completed the same journey.

Drake Equation

N = R* × Fp × Ne × Fl × Fi × Fc × L

N: The number of detectable extraterrestrial civilizations in the galaxy

R*: The rate of star formation in the galaxy

Fp: The fraction of stars with planetary systems

Ne: The number of potentially habitable planets per planetary system

Fl: The fraction of suitable planets on which life emerges

Fi: The fraction of life-bearing planets on which intelligent life emerges

Fc: The probability that a civilization emits detectable signals

L: The length of time such a civilization remains detectable

The Drake Equation attempts to estimate how many detectable extraterrestrial civilizations might exist in the galaxy.

The Great Filter

The Great Filter is the theory that one or more extraordinarily difficult barriers exist between the earliest stages of chemical evolution and a civilization capable of reaching the stars. These barriers may explain why detectable extraterrestrial life appears to be so rare.

In the game, a Great Filter can halt, reverse, or completely end a world’s evolutionary journey.

Asteroid impacts, extreme radiation, ice ages, greenhouse effects, ecosystem collapse, supervolcanic eruptions, global pandemics, nuclear disasters, resource exhaustion, war, uncontrolled artificial intelligence, and cosmic catastrophes can erase billions of years of progress.

Some planets will remain silent forever. Some will harbor only simple life. A rare few may develop civilizations capable of reaching the stars.

An Ever-Evolving Galaxy

Compared with previous entries, the scale of the simulation has expanded dramatically, bringing tens of thousands of stars together within a far more expansive galaxy.

Cosmic time continues to advance as you explore. Discovered planets may progress through thirteen evolutionary stages:

Inorganic Matter

Organic Molecules

Self-Replicating Molecules

Prokaryotic Cells

Eukaryotic Cells

Multicellular Organisms

Intelligent Organisms

Tribal Society

Agricultural Society

Industrial Civilization

Planetary Civilization

Interplanetary Civilization

Interstellar Civilization

A planet’s physical conditions and evolutionary potential determine how far life may develop. Yet even the most promising world is never guaranteed to overcome every obstacle.

Survey the Unknown

Every expedition gives you a limited number of scans and interstellar jumps.

Navigate the routes between stars, decide which systems are worth investigating, bookmark promising targets, and search for signals of valuable resources or advanced life. Manage your survey probes and starship fuel carefully, and plan your route before the expedition can go no farther.

Venture Among the Stars

Enter scanned systems, pilot your ship between stellar and planetary orbits, and inspect celestial bodies at close range. Each star and planet has its own appearance and a collection of physically inspired properties.

Survey these celestial bodies to recover minerals, organic matter, biological samples, and research data documenting intelligent life.

From Discovery to Expansion

Enable automatic exploration to let your ship jump, scan, and investigate star systems on its own, keeping the expedition moving without constant input.

Build outposts in remote systems and use stargates to discover new sectors, pushing the frontier ever deeper into the galaxy.

How many civilizations will you discover—and how many will vanish before you arrive?
