This is a new strategy game about factories and automation from the creators of the Factorio Ultracube mod.
The game takes place on a planet that has appeared in the outer reaches of the solar system. Players will lead an expedition to uncover the secrets of this “guest.” Build complex automated factories and production chains on the surface of this alien world to enable further exploration of its subsurface.
Players can work alone or with friends , constructing structures around labyrinthine caverns and exploiting the alien resources hidden beneath the surface. What secrets will be uncovered and what dangerous threats will arise from their activities remain to be seen.
Substructure will be released in Early Access on PC in 2026.
