Players familiar with the factory-building sim genre might compare Techtonica to titles like Subnautica, Astroneer, Deep Rock Galactic, and Satisfactory. After all, YouTube commenters on the announcement trailer point to those games, among others. Glinert and the rest of the Fire Hose team are fans of those aforementioned games, and he recommends everyone to check them out. However, there are some key ways that Techtonica will set itself apart from its competition.
Techtonica is a game set in the caverns of a mysterious alien planet. Surrounded by bioluminescent flora, you'll have to mine materials and explore the caverns to uncover the mysteries of this strange world. Although you'll start off with hand tools, you'll be able to work your way up to automation and gradually build factories that sprawl throughout the caverns. It looks like you won't be restricted by the shape of the world, either -- you'll be able to destroy terrain and even uncover hidden caves.
If you're hoping for endless new things to discover, though, you might be disappointed -- one of the developers says that the game world will be handcrafted. That said, you won't have to dive into the underground alone; you'll be able to play this upcoming game in four-player co-op.
