Alpha 0.15 :: Surface Exploration

Alpha 0.15 is now available on Steam! This update took longer than previous updates, and longer than I would have preferred, but there are a lot of great new features, updates and fixes. I’m especially excited about the planet exploration content.


Planetary Exploration

Operations Center

Colonists can now research and build an operations center and map table which allows for remote viewing of the planet surface. There are many new discoveries and resources to be found and exploited.


Remotely controlled vehicles allow for surface exploration, biome scanning and resource harvesting.

Surface Exploration & Mining

The Distance Operated Geo Explorer, or D.O.G.E, will allow colonists to scan biomes for new discoveries and resource information, while the Beetle Miner will allow for resource extraction and hauling.

Biologist Job Role

The Comm Officer has been fired and the new Biologist job position has been added. The Biologist will be responsible for tackling fish-related tasks.

New Discoveries & Research

Many new discoveries and research projects have been added for unlocking new, and some existing, content. Alien Flora/Fauna will now need to be discovered by scanning surface biomes before they can be researched and grown.

Notable Changes

There have been many tweaks and changes to existing craft recipes and construction material requirements. Construction and mining times have been reduced. Colonists will no longer die quite as quickly from starvation. There have been some minor graphics changes, and the camera zoom distance has been increased. These are just some of the changes.
For the full list of additions, changes and fixes, see the release notes below.
