changedSubstructure is our take on the factory automation genre. It puts you on the surface of a rogue planet in the far reaches of the solar system, as part of a hastily-prepared expeditionary mission. You must explore this alien world and exploit its resources in complex production chains. But to truly understand what’s going on, your expedition must dig deeper. You’ll be able to build massive platforms to transport yourself, materials, and even entire parts of your production chains between the cavernous layers below the planet’s surface.
changedSubstructure can be played solo, or with friends in multiplayer mode! It’s also built from the ground up with modding in mind. We got our start as modders working on Ultracube , so we want to ensure that modders can work their magic from Day 1.
changedWe’re also excited to announce that we’re partnering with Hooded Horse as our publisher for Substructure! Hooded Horse has a strong reputation as a strategy game publisher, with titles like Manor Lords, Against the Storm, and 9 Kings in their catalog. We’re excited to have their support, and their resources will allow us to reach a wider audience, localize into more languages, and get additional QA support.
changedStay tuned for more updates on this partnership and the ongoing development of Substructure.

We build games for people who love the struggle. Games that make you lean in, not zone out. Games that don’t hand you answers, but demand that you find them. When you play one of our games, we want you to feel immersed in meticulously crafted environments and compelling systems. We want you to face challenges that are designed with precision and care.

This is the philosophy we’re bringing to our upcoming game, Substructure. Check out the announcement trailer, which premiered earlier today on the PC Gaming Showcase: Most Wanted edition:
