How co-op works
Up to four online players share the full campaign, carving destructible caverns and building one subterranean factory. The group divides mining, exploration, power, and production work, then connects machines and conveyor systems to unlock technologies and advance together.
About this game
Techtonica is a first-person factory automation game set in the bioluminescent caverns of an alien planet called Calyx. You and your friends work together online to mine resources, mold destructible terrain, and construct a sprawling subterranean production network while uncovering the planet's buried mysteries. This is true cooperative play built around shared progress and collaborative problem-solving.

The core loop revolves around exploring cavernous biomes, harvesting raw materials, and designing increasingly complex conveyor systems, power grids, and assembly lines. Coordinating who builds what, dividing extraction duties, and optimizing logistics as a team adds layers of strategic depth and keeps the factory from becoming overwhelming.
Online co-op lets you and your group construct the same underground empire together, making communication and planning essential as production scales up. Long-term sessions reward patience and teamwork, turning incremental upgrades into satisfying collaborative triumphs as you dig deeper and piece together Calyx's secrets.

Frequently Asked Questions
How many players can build together in co-op?
The game supports online co-op multiplayer. You'll be working together to build the same shared factory and make progress as a team.
Do we share progress or does everyone have their own factory?
You share progress completely. Everyone works together on the same underground factory, so all mining, building, and story progress is collaborative and persistent for the entire group.
Can I play this casually or does it require long sessions?
Techtonica rewards longer sessions and patience as your factory scales up. It's designed around incremental upgrades and complex logistics, so while you can drop in and out, the most satisfying moments come from sustained teamwork over time.
Is voice chat important for co-op?
Yes, communication is essential. Coordinating who builds what, dividing mining duties, and optimizing conveyor systems together requires planning and discussion, so voice chat will make the experience much smoother.
