About the game
You start at the edge of a galaxy and work your way toward its dangerous core. Along the way you mine asteroids, loot wrecks, haul cargo and fight pirates. Most of the time goes into building. Your ships are made of blocks that you place and scale yourself, and what you mine and loot goes into better materials, turrets and systems.
Friends join you online in the same galaxy. You can team up in an alliance to build stations and take on pirates and enemy factions. Two of you can also share one ship, with one player steering and the other firing the guns. Fighting each other is optional.
It is a slow, open game with few fixed goals, and the first hours have a learning curve. You can play it alone as well, so co-op is one way to play, not the whole game. It suits friends who like to build and set their own pace.
