Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“As the sole developer of Mercury Fallen, early access is a great way to support the project and build a community of players that can assist in its development through feedback, reporting and exposure. The game has already benefited greatly from community feedback and through Early Access I hope to continue to grow the community as the game evolves. Join the adventure and help make Mercury Fallen the best it can be.”

Approximately how long will this game be in Early Access?

“While the game is very playable and enjoyable, there is still ground to cover with new content and updates. As a sole developer it's challenging to properly estimate how long it will take to get to final release. I'm dedicated to releasing regular updates to the game and currently plan to release in 2019.”

How is the full version planned to differ from the Early Access version?

“The focus of Mercury Fallen is building and exploration. Many of the core elements of building and management are in place, but will continue to be expanded upon. As development continues more focus will be put on exploration with the addition of discoveries, surface expeditions, story content and more.

Planned Features

  • Expanded technology tree
  • More crops and natural resources
  • Alien artifacts
  • Additional Cloning options / genetics
  • Trading
  • Planet Surface construction
  • Additional Story content
  • Various Surface exploration and exploitation
  • Support for player created mods

What is the current state of the Early Access version?

“The game has many hours of content and has been enjoyed by many users. The game contains most of the core elements that will continue to be added upon. In the current version of the game, the player can mine and grow resources, refine materials at crafting stations and expand the facility with additional rooms, machines and decorations. Manage colonist quirks, ailments and customization options. Explore and exploit the planet surface. The focus of the game is to build, expand and explore.

Players can manage power/water distribution, resource management and more. The game has a solidly playable and enjoyable foundation and I will add even more great content.

Current Features

  • Mine and grow raw materials
  • Refine materials at various stations
  • Design and build facility rooms, machines and decorations
  • Manage colonists’ jobs and needs
  • Handle colonists’ injury and ailments
  • Control colonists’ names, jobs and outfit colors
  • Research new technologies
  • Explore the planet surface for discoveries and resources
  • Take advantage of procedural generation, so that each new game is a new experience.
  • Grow clones, build robots and find additional colonists hidden in collapsed areas of the map

Will the game be priced differently during and after Early Access?

“The game will most likely increase in price after early access.”

How are you planning on involving the Community in your development process?

“Most games are only as good as the community behind it. As a single developer, it's not always easy to address all individual concerns, but I am eager to communicate with my audience via email, community forums and social media. I do my best to listen to player feedback and deliver on what makes sense for the game. I also plan to involve the community in optional test versions of the game before main game updates.”

Developer Log #44 :: Mods 'N' Modes

Hope everyone is having a great new year so far. I have some big plans for 2019. First up is an update that focuses on bringing initial mod support to Mercury Fallen.

Mods
The next update will add in official support for XML mods that can tweak existing content or add new content such as additional languages. Mods that add new artwork and Steam Workshop support are currently being investigated, but may not make it into this update. This is only the beginning, and further support will be added in future updates.



A Test Build will be available next week for those who want to test mod support. Your feedback will be very helpful in identifying what the community wants and needs. Additional information and guides will be made available for those interested in creating or using mods.

Display Modes


While mod support is the major focus of Update 19, I've also added new display modes for the surface map. The Discovered Biomes display mode shows discovered biomes in green and undiscovered biomes in red. This will help explorers track down missing biomes.

Additionally there are display modes for temperature, moisture and elevation. While these tile attributes are not critical at the moment, they will play a part in some of the planned content in development.

What type of mods do you want to see? If you're interested in creating mods for Mercury Fallen, please reach out and let me know the types of mods you want to create. Thank you all for a great 2018 and I look forward to creating some exciting new content in 2019!

Update 18 Now Live!



Howdy Pioneers!
 

Update 18 is now available, with many additions, changes, fixes and performance tweaks. A big thank you to to everyone who provided feedback on the test build.

 
Facility Minimap


View your entire facility with the new facility minimap. The minimap shows your facility, camera view area and colonists. You can now quickly navigate to different areas by clicking on the minimap. Speed and overlay controls have been updated and shifted to new positions on the screen to accommodate the new minimap interface.

 
Robot Recycler


The robot recycler finally lets you scrap robots you no longer need and get some resources back. The robot info panel now has a recycle button which will instruct the robot to be recycled. The robot will seek out the first available robot recycler and be recycled.

 
Save Game Interface


A new save game interface has been added that allows you to create a new save game, overwrite an existing game and name your saved games. An auto save feature has also been added. By default, the game will auto save every 10 minutes, but this can be adjusted or turned off in settings. The Quit To Main Menu save confirmation has been removed, as the game will now generate an auto save when returning to the main menu.

 
UI Tweaks


I've made minor tweaks to various UI elements, but the most notable are the changes to the color picker and main menu interface. The color picker has a new look and many more color choices. The main menu has been updated and has a Continue button, which will load the latest saved game.

 
Fixes & Performance Tweaks
Thanks to your support I've been able to hunt down and fix various bugs that affect colonist behavior and more. Several tweaks have been added to improve performance during the later part of the game. Keep those bug reports coming! :)
