Begin with one colony and a single home star, then expand across a galaxy of alien worlds - researching exotic science, designing your own fleets, and bending rival empires to your will through diplomacy or open war.

Hand any colony to a Governor and let it run itself Design Your Own Fleets Engineer warships from the keel up across five hull classes, from nimble scouts to colossal capital ships. Combine more than 80 components - power cores, drives, scanners, shields, and an arsenal of exotic weaponry. No two commanders fly the same fleet....
