What is Avorion?

A third-person, open-world space sandbox where you build ships from scalable blocks, explore the galaxy, mine, trade, fight, and manage fleets alone or with other players. Starting at the galaxy’s edge, you advance toward its dangerous center while investigating a past catastrophe and the alien Xsotan.

Not for you if...

−you want a deep, reactive economy and dynamic factions
