About This Game

In Solar Expanse, you take the lead of one of the early XXI century space exploration companies. Your goal will be to reach the planets, moons and asteroids of the system in order to mine and colonize them.

Optimize the costs and schedule of the flights. Mind that each object is in constant motion, so exact planning is crucial. Utilize the gravity effects and slingshot your rockets further beyond.

There is a multitude of objects in the asteroid belt alone. Some are made of water, others might contain precious metals. Deploy various telescopes, arrays and probes to know the system better and plan your next flights. Scan for the most profitable and useful materials. Research new technologies

Send your rockets and deliver the asteroids to Earth or colonies. Gain the profits to expand your corporation and start the projects on much larger scale. Or just drop the asteroids on the planets and moons, either to terraform or ruin your competition plans...

In time, you will get contracts to establish permanent bases on various objects. Build fuel stations, launch sites, space catapults, elevators and entire colonies!

Your ultimate goal will be to make the moons and planets of different systems habitable. This task will take centuries, enormous resources, technologies and thousands of rocket flights. Drop the water asteroids from the asteroid belt on Mars. Mine Io and Titan for necessary resources.

Once you are done with the Solar System, build an interstellar ship. Once the game is fully released, you'll be able to venture into real and generated systems, such as Alpha & Proxima, Centauri, Trappist, Gliese & Kepler… you name them!
