Factorio: Space Age continues the player's journey after launching rockets into space. Discover new worlds with unique challenges, exploit their novel resources for advanced technological gains, and manage your fleet of interplanetary space platforms. For more information about what comes with the expansion, check out our Space Age content page.
I have it on Steam, but I can understand wanting it DRM-free. I don’t think Wube would try some corporate DRM shenanigans though.
If you buy it on steam you can then reclaim it DRM free on Wune’s website
