Early Access Game

Get instant access and start playing; get involved with this game as it develops.

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 #36 :: Biome Exploration

A lot of work has gone into the planetary exploration update and I wanted to cover some of the expected new content.

Vehicles


Since the last developer log, vehicle construction has undergone some design changes. Vehicle construction now uses predefined vehicle types instead of a modular vehicle template system. This felt like a better fit for the game and more consistent with existing systems. I do still plan to have separate vehicle tiers and the ability to find and equip upgrades to vehicles, but these features won't make it into the next update.

Two vehicle types will be available in the next update for exploration and mining. D.O.G.E., Distant Operated Geo Explorer, and the Miner, proper name pending. The D.O.G.E. is used to explore the map and scan various biomes to uncover resources and make discoveries. Once resources are known for a given biome they can be ripped from the ground using the Miner.

Biome Scanning

After uncovering new biomes, they will need to be scanned. Once scanned by D.O.G.E. you'll discover information about that biome including potential flora, fauna and what resources can be mined.

Biome Resources


Each biome will offer different ore resources and potential discoveries.  Mined resource amounts will also depend on a given tiles elevation and are shown in percent. When a Miner works a given tile it has a random chance of getting one of the shown resources each time it mines up an item. Once a miner vehicle inventory is full it can be sent back to dock with the facility to drop of what it gathered.

Discoveries


A lot of additional discoveries are being added. Existing alien flora and fauna will now have to be discovered on the surface before they can be grown in the facility. Each biome is also a discovery item to provide additional information about the various alien biomes.

Expeditions
Expeditions that include the colonists is being pushed back and won't be part of the next update. There is a more work I want to put into the POI system to make colonist expeditions more interesting and varied. The next update is just the start of more surface content to come and will serve as a solid foundation for further expansion.

Vacation
On a more personal note I'll be on vacation next week to Washington D.C. to explore the various museums. This is the first real vacation I've had in over 10 years so I figured I was past due. I'll still be checking in on things here and via email/twitter/discord, but I won't be able to do any development until I return.

As always be sure to follow along with the latest screenshots and info:

Alpha 0.14.5 Now Live!



Alpha 0.14.5 patch update is now live! This is a smaller update to fix and improve various elements of Mercury Fallen while development continues on the planetary exploration content update.

New Game Interface


The updated new game interface offers new map sizes. Map sizes are now 80x80 (Small), 100x100 (Normal) and 150x150 (Large).

 
HUD Inventory


The global inventory display now has a background and additional options. You can choose to view in list or category mode, toggle the display of items with zero quantity and sort alphabetically or by quantity.

 
Mining/Deconstruction Highlight


Tiles marked for mining and deconstruction are now visually distinct.

 
Additional Improvements


Notifications are no longer hidden behind open info windows, but instead will slide out with and show to the left of info windows. Edge scrolling now works on the right screen edge with an open info window and diagonal edge scrolling at the corner of the screen now works as well. The screen panel on the medi-bed will now light up when a doctor is treating a patient.
