Alpha Demo 1.1 Update

I’m very excited to announce a new version of the Mercury Fallen Alpha Demo. This update should hopefully resolve a lot of the game breaking bugs as well as add several new features/improvements to the game. Please contact me and let me know if you find any bugs, have some suggestions or just want to say hi.

Starting Conditions

There have been a lot of changes to the starting conditions of the game. Players will now start with the utility room and engineering room already built. A power generator and the new bio-refiner are also made available at the start of the game.

Structure resin is now craft-able at the bio-refiner station (engineer profession). Dirt now drops mineral compound when mined which is refined in to structure resin. Some starting structure resin can be acquired by mining wall debris.

Clone Chamber

The cloning chamber was not functional in the previous version and this was not made clear. My apologies for any frustration caused by that, but the clone chamber is now functional and ready to go. While the cloning process is planned to be a lot more detailed in future, the current iteration allows users to start popping out new random clones to expand the work force. The clone chamber does require both power and water to function.

Water Supply

Water conduits have been added and the water pump is now functional. Much like power some machines will require water and need to be connected to a water pump using water conduits.



There were certainly plenty of bugs caught in the last version and I’ve managed to track down and get them fixed. Many users complained about the fridge not working and that was definitely my fault. Before releasing the demo I had made changes to how inventory worked and the fridge was set to only store 1 item (whoops). Colonists also had no clue what to do with items they had in their hand that couldn’t fit in storage. These, and many other, issues have been resolved.

A big thanks for all the great feedback that helped me track down these issues.

    • Structure resin (used to build storage and other structures) previously dropped from dirt. Wall debris now drops initial structure resin when mined. Additional structure resin can now be crafted at the bio-refiner using an engineer with mineral compound which is mined from dirt.

  1. For some reason my guys keep going in a walking animation but they are stuck at their place even though there is plenty of room to walk, why is that?

      • Thanks for playing! That is a good question and certainly odd behavior. Please use the contact form on the contact page of the site to submit a report. Include any additional relevant information. I’m not sure why this is happening, but these types of issues are certainly under investigation. 🙂
