The second game developed by Mirko Seithe and made on Linux, Kubifaktorium, a voxel colony management and automation game is now available in Early Access. Note: Key provided by the developer.
Build, manage and grow a thriving settlement in Kubifaktorium, a voxel-based colony management and automation game. The game features multiple biomes to explore, plenty of resources to exploit, complex transport systems and automations to build and interesting production chains to master.
I've played a few hours of it and found it to be pretty interesting, it has quite a few tutorials that are recommended to go through and they do a good enough job at getting you started. Already reminds me somewhat of Settlers and other similar games, especially with the zone system with you needing to expand your zone to be able to build more. Has a really great concept, with a sweet blocky visual style and a great gameplay pace allowing you to play it as you please.
Seithe has some good plans in place for future updates including Steam Workshop modding support which they said will be "soon", along with an automated production system they say will be due around "Q4" this year and more biomes.
For the Early Access timing, they're planning to remain there for no more than two years like their previous game BossConstructor (which also supports Linux).
