Sigma Draconis Wiki Home ⤴


Sigma Draconis Expanse is a heavily-modded Space Engineers server, themed after The Expanse TV show and book series.

Expanse is PvP-enabled, with plenty of PvE NPCs to fight as well. If you’re not too keen on PvP, rest assured that it’s easily avoidable outside of known hotspots and rare moments of bad luck.

Originally released in 2021, SDX is on its second iteration (SDX2), launched in 2026.

Please read the Server Rules before joining the server!
