About the Game
Welcome to the strangely beautiful, bioluminescent, and mysterious sub-surface alien world of Techtonica. You’ll begin with only the basics for digging, mining, and resource production.
Full Story Campaign
‘Techtonica’ is the only factory automation game to offer a complete, fully voice-acted campaign to play through. Something unknown awaits you beneath the surface of Calyx, Groundbreaker. Untangle and revive the efforts of an expedition gone wrong with the help of cubic companions who have motives, personalities, and secrets of their own.
Build Machines
Discovering everything in Techtonica demands unique equipment, power, and resources. Build specialized machines to optimize gathering and production as you arm yourself with the tools needed to dig higher to the surface.
Explore & Discover
Exploration pays off in Techtonica. Tunnel your way to massive ore deposits, research-rich facilities, and hidden caves to find new technologies, scan aging artifacts, and learn more about the mysteries of this world.
Terraform Entire Caves
Obliterate stone walls with a black hole gun. Drain deserts of sand with towering pumps to uncover what lies beneath. Sculpt the world to fit your subterranean vision.
Create Beautiful, Sprawling Factories
Take your mining operation to new depths by constructing sprawling, efficient factories. Automate production lines with Conveyor Belts and Inserters and a wide cast of machines. Deck out your factory with Eco-Brutalist Base Building parts.

Version Information
Steam Patch Notes
Official update history
Please note: this hotfix is limited to the late-game progression blocker discovered in the PULSE Room. We’ll have a more comprehensive patch in the new year, but we wanted to get you a fix for this progression blocker before we leave for the holiday break.
What was the problem?
Some players worked through the new Base Building content introduced in v0.2 of Techtonica only to find themselves locked in the late-game PULSE Room as they neared the conclusion of the new narrative and quest lines. These players could respawn, but they couldn’t complete the remaining objectives.
What was fixed?
Groundbreakers who previously visited the PULSE Room and had its door shut on them will now find that the door has opened again. A similar issue with the initial door aboard the Excalibur (leading to Paladin) shutting itself should also be resolved. Signage for both doors might be slightly off, but this will not impact your experience.
Lingering issues and workarounds
Players who skipped the Freight Elevator cutscene may still experience issues, but there is a workaround. If you first replay the skipped cutscene from your Log menu, you can walk into the waters around the elevator afterward and trigger the next part of the story.
If you have finished the Freight Elevator cutscene, paid an initial visit to PT XRAY, and discovered the Mining Drill MKII but have not yet received a signal to the PULSE Room, make sure that you return to PT VICTOR.
Ah! If you’ve built a truly massive base, please stand somewhere in front of VICTOR that isn’t too high off the ground. The radio can’t see you up there, Breaker.
Once you return to the PULSE Room and witness the cutscene that follows your final interactions in that room (no spoilers!), you will have reached the end of narrative content for 0.2.
Thank you for playing! See you in 2024!
