Alpha 0.12 :: High Priority

Mercury Fallen Alpha 0.12

I’m super duper excited to announce that Alpha 0.12 is now available on Steam! This update is packed with new content, updates and lots of fixes. While the priority system was certainly a focus for this update there is a lot of additional content that has gone in to this update.

Important Note
Existing save games from 0.11 will not load properly in 0.12. Please start a new game in 0.12.


Priority System

Alpha 0.12 :: Priority System

The new job priority system allows you to set the priority order of job roles per colonist. This is visible in both the colonist info window and colonist management screen. Higher priority jobs will be performed before lower priority jobs.
This is just the start. Additional priority options will be coming in future updates

Object Placement

Alpha 0.12 :: Object Placement

Object placement has been overhauled and a new visible footprint is shown when placing down objects. This new system helps to enforce proper walk areas for colonists as well as stopping colonists from walking through objects. More information about building objects can now be found in the in-game manual.


Alpha 0.12 :: Manual

A new in-game manual has been added that can be access by opening the facility management screen and selecting manual from the top button bar. The manual is not content complete, but is a great starting point for new and existing players.

New Objects

Alpha 0.12 :: New Objects

The Tech Printer machine has been added which is used, by the engineer, to create tech items such as electronics and mechanical parts. The smelter has been re-designed and a new storage container option makes it’s way in to the game.

More Audio Effects

I’ve added many sound effects for various actions/machines to help liven the game up a bit. There is still more to add, but this is a good first step towards a more audible environment.


Alpha 0.12 has a lot of great new additions, changes and bug fixes. Let me know what you think.
