Starting with a small group of colonists, you're tasked to mine resources, refine materials, build structures, and innovate with new technologies. Across generations and centuries, you'll expand your settlement into a thriving civilization and terraform the planet to make it your new home.
Prosper Through the Ages
Colonists are born, educated, work, retire, and die. Over generations, their needs may evolve, dedication may diminish, and mutations may arise.
Principle of Mass Conservation
Nothing simply disappears. Every bit of material transforms into something new. Resources follow their own cycles, involving production, consumption, and recycling.
Food
Transform barren soil into fertile farmland using materials from your surroundings. Melt ice for water, use the water to grow food, and then purify it for reuse. Balance these elements and watch your colony thrive on the food you produce.
Atmosphere
Convert exhaled carbon dioxide back into oxygen for your colonists. Tackle industrial pollution and manage various gases. As your base expands, maintaining atmospheric pressure becomes essential.
Industry
Begin with mining ores and minerals, refine them into advanced materials essential for constructing buildings and crafting items. With each step, transform raw resources into the foundational elements of your expanding colony.
Terraformation (during EA)
Transform the planet's surface and temperature to make it habitable by managing temperature control, ecosystem growth, and water resources. Create a breathable atmosphere and turn the planet into your new home.… And More
- Research: Unlock new possibilities, buildings, and recipes via the research tree.
- Power: Generate and store energy from diverse sources.
- Logistic: Manage logistics of your expanding colony with drones.
- Game Events: Strange things can happen in the cosmos. Some events might be nice, but some, well you will see for yourself.
- Space Management: Deal with the material you don't need.
- Luxury Food and Goods (during EA): Produce various items to keep colonists productive.
- Free time (during EA): Meet colonist social needs to prevent unrest.
- Temperature (during EA): Control the temperature within your colony and on the planet.
- Mutations (during EA): Turn the mutations in the alien world to your advantage.
See you underground!

[u]Balancing & New Features[/u]
* Initial visibility on maps around ship reduced.* Speed of unlocking new research has been adjusted to steadily pace.
* Ice Melter research moved to early stage & Ice Melter recipe upgrade has been removed.
* Moss fixed and rebalanced.
* Vent Center updated to start working a bit later. (If other filtering/producing buildings are filtering gases, Vent Center would remain inactive or as support to those buildings. That results longer life of Vent Center).

Happy colonizing!
Hello Colonists!
Were excited to announce the release of our v0.65 Update for ExoColony: Planet Survival! This update includes tweaks, bug fixes, and performance enhancements to improve your gameplay experience.
[u]Edicts[/u]
* Added new edict:* Stable Population - While active, whenever Colonists die, there will be automatic replenishment with a newborn.
* Updated descriptions to clarify edict functionalities.
[u]UI[/u]
* Fixed tooltips in the Research window so they now display correctly.[u]Graphics[/u]

[u]Bug Fixes[/u]
* Advanced Foundations & Advanced Lifts now correctly grant increased speed bonuses.* Storages can be now turned off. All items are moved to other storages. Same situation happens when the storage is being demolished. So the stored items are not lost!

* Atmosphere & Pressure fixed - There were reports that whatever you do, there is a shortage of nitrogen in the atmosphere. In the end everything was set correctly, but 5x-10x lower than intended. So when the Ship Ventcenter was depleted, there was only an option to merge new rooms to get extra pressure. Now Nitrogen Generator generates more Nitrogen and consumes less Soil. Same rules go for Oxygen Generator, Pollution Recycler, Electrolyzer and Hydrogen Power Generator
[u]Performance[/u]
* We made significant optimizations in colonist's pathfinding. So there should be no longer spike lags with higher counts of colonists.Happy colonizing!

Best,
The ExoColony Team
Today it is not an usual update. We had a lot of meetings in the past few weeks, because we needed to see the bigger picture of where our game is heading. Thanks to our testers, who reported that information and game mechanics was really fast going and in overall a lot of mechanics were fast paced.
So we decided to make a couple of big changes in gameplay, which I can already confirm were pretty good decisions and the game is already looking much cleaner, slower paced, clearer and more chill to play.
For example:
Well that was the couple of main changes which are undergoing. In a few weeks we should put it all together.
Cheers,
Your ExoColony Team!
[u]New Features[/u]
- [u]New Tier Cycle - Research:[/u]
[list] - We understand that colony sim games can be overwhelming with all the things you need to learn to make things work. So we decided after a small tutorial YOU will be in charge of what do you want and need to do next. Running low on storage? No problem just research bigger storage or store into dumpsites, etc.
- Each colonist will produce passively research points. Higher educated colonists will yield higher amounts, but with no education you can expect very little gain. But each researcher in the Research Center will help you with points.
[list]
[u]Changes[/u]
- Farm Incubator now produces more food (Basic Food production per recipe increased from 0.3 to 0.4)
- Mining time decreased from base 10s to 8s - (In the early stages of game you spend lot of time digging, so we speed it up a little to keep player more engaged on things that really matters.)
[u]Fixes[/u]

[list] - Transforms Soil and Clean Water into Food
- Water Purifier (Food)
