Early Access Game

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

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“As a small indie studio we need all the feedback we can get. Adding new features and balancing the game dynamics is a quite complex task within the global simulation of each planet. Additionally the income of early access helps us to stay independent. We want to take the time to evolve this game into a little sensation. Something that has never been played this way before. The first planet colonization and climate survival thriller game.”

Approximately how long will this game be in Early Access?

“We plan to release Imagine Earth in late 2016.

There is a new alpha release every 3 to 4 weeks.”

How is the full version planned to differ from the Early Access version?

“Currently there are three big things left to do:
1. Add more interaction with other (AI) companies and their cities: Trading, taking over, sabotage, ...
2. Make the general gameplay more diverse.
3. Iterate until the whole thing is perfect ;-)”

What is the current state of the Early Access version?

“Please read the feature list in the game's about section.”

Will the game be priced differently during and after Early Access?

“No, the release price will be the same.”

How are you planning on involving the Community in your development process?

“We need your thoughts, ideas and direct feedback on what you experience during gameplay. To keep you updated about the actual development process we are writing a friday report every week and there's a major update release once a month. The complex interconnections between the buildings are a hell of a balancing job on which your opinion is highly appreciated. Name the features you would be most excited about and let's make this thing a unique experience together.”

Alpha 22 "Emission Levy"

Another month is over and Alpha 22 is ready for you. In short:

  • Emission levy to balance global pollution
  • New take over rules
  • New preview images in tech menu
  • Harvesting forests and mining rocks earns goods
  • Cold temperatures reduce the harvest of your farms
  • Changed savegame directory structure
  • Porting to MonoGame prepared
  • Bugfixes and balancing ...

Emission Levy

The emission levy (as shown in the image above) is a new rule introduced to add some fairness to the aspect of global pollution. Once the climate balance of the planet falls into negative, the companies with high emissions have to pay charges to the companies whose emissions are below the average. A good incentive to reduce emissions.

New Take Over Rules
The last alpha version 21 introduced to possibility to take over opponent cities by buying 50% or more of their taxes. We have collected your feedback and added our own ideas to further refine this.

The value of a colony itself is now much higher to make sure freshly build colonies are worth more than 5-10% shares. Additionally we changed the rules for watchtowers (!):
  • A watchtower that has no connection to a colony center will be lost. This can happen when (A) an opponent takes over a colony or (B) a connecting watchtower is destroyed.
  • Watchtowers that have no owner and are adjacent to your colony can now be taken over by paying some money.
This makes the whole process of taking over opponent colonies a bit more interesting and challenging.

New Preview in Tech Menu
All buildings and their upgrades have received new preview images that are show when hovering them in the tech menu.

Harvesting Forests & Mining Rocks
With the new version you no longer earn money when harvesting forests. Instead you receive goods every tick until you cancel the harvest process or the forest is uprooted.

This is also the case for rocks. Mining them now also gives you goods that can be used by your population.

Important: Harvesting forests with the chainsaw tool and blasting rocks will give you only a part of the goods and you will need a storage to keep them, because everything is earned at once.

Influences of Temperature
The temperature of a planet field is shown at the bottom left of the screen in the field info panel. Farms and some forest types are affected by cold temperatures. The following screenshots shows an industrial farm that was build on a field with a temperature of -8°C. This extremely reduces the amount of food produced, as shown in the message panel.

Changes to Savegame Directory Structure
We have simplified the directory structure of savegames (left old, right new). When you start the new released version of Imagine Earth everything should be changed automatically. However, it's always possible that something goes wrong. If savegames are missing please check the directory structure and write a support request to

MonoGame Portation
Imagine Earth has been developed using Microsoft XNA - an easy game framework that is no longer in active development. Luckily members of the XNA community started to develop MonoGame which now can be used as an open source replacement. This makes it a lot easier for us to find bugs and enhance the performance of Imagine Earth (e.g. by using DirectX 11). In addition it enables us to port Imagine Earth to other platforms, though this is not something we plan to do at the moment.

Long story short: During the last weeks a lot of time went into porting Imagine Earth to MonoGame - especially sounds and music. Since a new technology might also introduce new bugs we will start a public test in the next days. Stay tuned if you are interested in helping us to make sure everything runs smooth.

Alpha 21 "Taking Over!"

Here is our Easter release: Alpha 21 "Taking over!" - 10 new features - all in one basket. Please leave a comment to let us know how you like it!

Take over colonies
of other companies
You can now take over your opponent's cities in free play and competition mode one by one. All you need is 50% of their shares. When taking over a city you give up shares with the same value as the city and you have to pay some additional money. And then... it's all yours! A new economic way to world domination.

Bloom & Blur
We added some up to date visual effects, namely bloom and blur to the game. See how beautiful the sunlight is now reflected on ocean water and the shiny metal roofs of your colonies, as well as bonfires, cities lights and crystals are glowing in the dark.

In addition the research, technology and stats screens received a smooth blur effect in the background.

New Info Panel
Long since there was more to be know about the ground types and fields on “Imagine Earth” than the old info panel could visualize. So here's the new one with less bars and a fixed window position. Fertility, pollution and temperature are very important factors that now each have their own slot and are readable in a clear way.

With this interface change made we also decided to let the fertility of a field influence the food production. This means the bonus on a fertile field now depends on the exact fertility and the handicap on a desert field depends on how much desert-like the field really is. As a result it's now much easier to find an acceptable field for a farm - and it feels less like a puzzle game.

Multiple Fossils & Ore
With the new Info Panel there are now up to three different fossil resources in one field. We therefor removed the general fossil type because it was confusing. Now every fossil production building (e.g. coal power plant) will only be influenced by it's corresponding fossil resources (e.g. coal).

Ore is a new fossil type that boost the productivity of mines.

Ideon Bomb & Item menu
The second items in the merchants shop are ideon bombs. As powerful as they are expensive, but finally a way to blast the small mountains out of your way that are hindering the expansion of your colony.

New Research: Blast
You can now research the blasting of rocks. This helps you to get rid of them much faster. It's more cost intensive but time is money, isn't it?

Earn Research Budget
with Science Points

Leveled city districts have a new very important function in the free play and competition game modes. They add to your amount of science points. This amount will unlock new research budget which allows you to unlock the blessings of latest technology achievements for your colonies. In addition you can also get some research budget at the merchant - for a lot of money.

Victory Point Notification
In the competition mode you will now be notified whenever you or a concurrent company earns a victory point.

Changed Victory Point Rules
To make sure the "highest ..." victory points don't jump around between the players we added a small change of rules to the victory points for quality of life, productivity and ground pollution:
When a player has received the victory point you need to exceed that player by 5% in order to take the victory point away.

New Communication Interface Graphics
Still needs some fine tuning... but much better than when these guys where just hanging behind the text boxes. If you ask me.

That's all for today, thanks for reading! Remember: Please leave a comment to let us know how you like it!

“The demo is quite charming... There's already evidence of a decent game”
Rock, Paper, Shotgun

“Imagine Earth is a refreshingly streamlined and charming apporach to civilization sims - and one with plenty of room to grow as it wades through Early Access.”

“This environmentally-conscious title may very well prove to generate news in the months to come.”

About This Game

Imagine Earth

Imagine Earth is a real-time world simulation. Your job as a colony manager is to explore and populate distant planets. Build up thriving and profitable colonies on a global scale without destroying your homeworld. Deal with threats like meteorite strikes, twisters and wild fires. Coexist and trade with natives, alien investors and hostile colonies, dig for Ideon crystals, pacify riots and master the perfect balance of production and consumption for many available constructs and technologies.

The Challenge

Raise great cities and satisfy their growing appetite for resources by building power plants, farms and factories. You will soon encounter the conflict between the profit goals of interstellar corporations and the need to preserve the living conditions for your people. As your colony grows it is getting a problematic impact on the planet in terms of exhaust emissions and pollution. The challenge is to deal with whole planetary ecosystems and their natural limitations in fossil resources and environmental resilience. Do research for renewable energy sources and develop sustainable production lines to avoid overgrowth and climate collapse on your new home world. Can you prevent tremendous desolation and lead your colony into wealth and prosperity?


  • Play on a globe instead of a map
  • Campaign with 6 missions and planets introduces into the gameplay
  • Goals guide you through the expansion of your colony
  • Development of over 30 colony buildings with individual upgrades
  • Global simulation of local pollution and worldwide emissions
  • Disasters: Chemical spills, oil slicks, radioactive contamination, wild fires, tornadoes, volcanoes, dying forest and growing deserts
  • Melting polar caps will raise sea levels and flood your coasts in case of global warming
  • Sandbox mode to generate and edit your own planets
  • Competition and Free Play mode let you build your colony in a race against AI players or for yourself.

Climate Change

Climate change is apparently a very underestimated threat in computer games. The idea behind Imagine Earth is to put the most serious background of latest human history into a thrilling and motivating game flow. In that context the game is an experimental world simulation or a climate survival thriller. It directs this quest to the player. What would your civilization end up like and what could you do if you were in charge and no one else around to blame? Imagine Earth offers the biggest possible freedom of choice to the player so he can find his own answers and development strategies.

“Your decisions will most likely lead into states where you have to rethink your whole way of playing!” - Jens Isensee, Design & Graphics

“Exploring the balance between growth and sustainability is the key to success in this game.” - Martin Wahnschaffe, Design & Code

One of the best planetary colonization games I played. Not only with beautiful graphics, but also smooth gameplay and story line.

Can only wish the strategy aspect became a tad deeper...

Early Access Review
The game combines resource management, technology planning, and careful positioning at a real-time strategy game pace. It is easy to pick up the basics, but definitely takes skill to get good at it.

The gameplay is great, despite the graphics not being the best on the market. Considering this is an indy title, it really needs to get more attention as a great addition to a difficult-to-please genre of players.

Look at the negative comments for the game - none of them complain about gameplay. Its all taste-based comments or something that's not an issue like expecting world-class graphics from an indy team. The negative comments don't complain about the gameplay, because the game is fun and challenging.

Would love to see how this game ends up at release. Fantastic game so far - This could become a benchmarking game for the genre.

-City building
-Interaction of buildings

Also what i like;

-Graphics are good
-Building is simple and easy
-Researchind and upgrading are not confusing
-UI is good
-Not boring

What i dislike;

-Technolgy should be better. Lack of tech

Gameplay: 9/10
Graphics: 7/10

Early Access Review
It's a simple yet fun game. I dislike early access games but after trying the demo thought I'd get it. Very glad I did. My advice is, if the demo is still here then give the game a try. If you enjoy it then you will like the game. There are other reviews that give details, but why read what somebody thinks if you can try it yourself! 10/10 from me.
