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 than 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 playable and enjoyable, there is still ground to cover with new content and updates. I tentatively estimate the final version will be released in late 2018 or early 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
  • More machines and possible upgrades
  • Explore the planet surface and uncover secrets and expansion opportunities
  • Discoverable items
  • Alien artifacts
  • Additional Cloning options and genetics
  • Deeper robotics system
  • Support for player created mods

What is the current state of the Early Access version?

“The game is in a playable state and has been enjoyed by many users via its initial release on platforms outside of Steam. The game contains many 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. 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
  • Recover corrupted data to learn new blueprints
  • Take advantage of procedural generation, so that each new game is a new experience.
  • Grow clones and find additional colonists and robots 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 between main game updates.”

Developer Log #25 :: Robots

This week I've been working on various aspects of the game for the next content update and I wanted to report on the progress so far. Robots are currently free labor as they can't die and don't have any needs to fulfill. It has always been the plan to have more requirements for robots as well as the ability for robot construction.

 
Robot Recharging


Robots requiring power is currently being worked on for the 0.11 update. Robots will need to be recharged at charging pads, similar to how colonists need to sleep. If a robot get's below 5% power it will get a speed reduction and no longer perform any job actions. Charge pads will be another branch of data recovery and the plan is to add one charge pad to the facility at world generation.

 
Robot Construction


The Robot Assembler is being added which will allow colonists to construct new robot workers. I'm still tinkering on the details on what control the player has over the quality of the robot output. This may be something that is added more simply at first and built on to over time. I am also working on a new type of robot which will allow players to mine floor tiles for additional resources.

 
Notice Icons


There is also more work going to into reporting information to the player and in that vein I'm adding in hovering notification/warning icons. These hover icons will show on top of objects to notify the player to issues such as an object having no power, no water, not enabled and more. This is a great way to see the status of objects at a glance.

 

The next update is shaping up very nicely and will have some great new content. What are your thoughts on some of the new features?
