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 #24 :: Test Builds

The response, on Steam, to Mercury Fallen has been awesome. A huge thank you to everyone who has played Mercury Fallen and for the great feedback. I am deeply humbled by the amount of positivity the Steam community has shown me. I am very happy to see gamers enjoying Mercury Fallen and there is a lot more to come. I have been actively working on the next update which will include fun new content as well as several fixes to bugs that have been reported.

Test Builds

One of the benefits of Steam is the Beta Opt-In support which allows developers to have separate optional testing/preview branches of the game. These optional game branches are a great way for the community to get involved with testing the latest and greatest content. It also serves to reduce the amount of potential bugs/issues in versions that go public to everyone.

Before major updates of the game come out they will first be available in the optional testing branch on Steam so that users have the opportunity to help test the latest content before it goes live to to the main branch. If you’re interested in testing out the latest content and want to help track down bugs click here for more information.

Alpha version 0.10 is now available in the optional test build branch. For more information on what is in the new version click here. Please keep all discussion related to the test builds in the test builds discussion thread.

Thank you again to everyone who has helped support Mercury Fallen so far. This is only the start and I look forward to working together to make Mercury Fallen the best it can be.

Developer Log #23 :: Moving Forward

Mercury Fallen was first released on Itch.IO on April 7, 2017 as a prototype demo. Shortly after that a full early access release hit Itch.IO and the response has been amazing. On October 16, 2017 Mercury Fallen will be available for purchase on Steam, as Early Access, and I’m super excited to continue to develop the game and grow the community. The Steam release is only the beginning. There is a lot more to come for Mercury Fallen and I’m very grateful to those that have supported the project so far.

This week I’ve been fighting off a cold which has slowed progress on the next update, but I wanted to go over some of the things I’ve been working on.


Decor
The plan has always been for decorative objects have a larger impact on game play and with the new decor system that is finally starting to happen. Various structure objects in the game will provide positive or negative decor to the surrounding tiles. As colonists walk around the positive/negative decor value will have a direct effect on their stress level. The uglier the environment the more stress a colonist will receive. Positive decor items, such as decorations, will help to reduce stress.

The biggest challenge I found when trying to implement this system was how best to visualize the decor of the environment. The end result was to create a color overlay which shows positive decor areas in green and negative decor areas in red. Areas that are white have no impact. I’ve added some new buttons to the bottom button bar to toggle different display modes for power, water and decor views.




Colonists will stop working entirely if their stress level is completely maxed out, which means managing decor and stress becomes more critical. In addition to decor I plan to add additional interactive stress reducing objects.


New and better crops
In addition to the new decor system I’ve improved the look of hemp and have started work on additional crops. The new glow bulb crop is currently planned to be used as an ingredient for cloth as well as a new meal recipe.




Those are just some of the things being worked on for the next update.
