Tellus: Save the Earth is a serious resource management game.

High Concept

Tellus is a game that challenges players to improve the global quality of life through the development of a sustainable global society.


The gameplay focuses on five areas of development: energy, production (food & industry), public health, environmental awareness, and earth observation. Each of these areas is represented by a "tech tree" that allows players to explore different technologies and policies.

The earth is divided into multiple regions, and each region has a number of cities representing the population of the region, and a handful of nodes upon which various power plants, factories & farms, etc. may be constructed.

The game starts in the year 2010 with each region's tech tree and infrastructure modeled on what it is in th real world. Play progresses through a span of 40 years at a rate of one year per minute (though the game may be paused at any time.) This pace affords players the opportunity to complete a game in about an hour, inviting replay to try out different strategies. Ending the game by 2050 avoids the pitfalls inherent in forecasting too far in the future (few people alive 40 years ago were able to predict much of what the current world looks like, and the rate of change is accelerating.)

A principle goal of this project is to produce a video game that raises awareness about and teaches the importance of using earth observation systems and data to solve real world problems. The basic message is that policy decisions should be based on facts. The primary win-condition of the game is to raise the quality of life for all of Earth’s population, which is very closely tied to the well being of the Earth itself.

The game is being created with Unity3D.

Target Audience

Tellus is primarily aimed at children ages 9-18. It is intended that the game will be localized for multiple regions in order to reach an international audience.

Target Hardware

PCs running Windows Vista, Windows 7

Macs running OS X and later

May be run in a browser.

Future plans include iPad and other tablet computers.

Fifteen weeks have passed and the team has made good progress. The Alpha 5 Build includes new aquaculture options that offer some great alternatives for food production and allow water nodes to be used for something other than energy production. Coming soon: more uses for water nodes!

We've also addressed a number of bugs. We're very happy to have had another group of students join the team as official QA testers, so you can expect a steady improvement in the stability and overall quality of the game as development continues. And continue it will! This summer semester we have set some ambitious goals for ourselves:

  • More improvements to the GUI - cleaner, slicker, and most importantly, more informative
  • (Filterable) event log so that you can review the messages you may have missed
  • Research timers so that investing in new technology won't produce instantaneous results
  • Completely revised Earth Observation tech tree based on the information we get from EO scientists
  • Better game endings (with more information about how you did)
  • More music and sound effects
  • More player preferences settings for gameplay, audio, etc.
  • And, hopefully, several more features and enhancements that address the many suggestions that we've received

Thank you for your continued interest and support,
The Tellus Team

I would just like to keep everyone up to date on what's going on with Tellus.

We are currently working on re-structuring our GUI to make it more user friendly and light weight. We would like everyone's input on how the changes are coming with the next few updates.

We love player feedback, and we will review all feedback that we are given.

Enjoy the game!

A huge GUI fix to Tellus Alpha 4 has just been submitted for download. Once it is approved, you will see that our region tech research GUI has a much nicer feel.

Many more editions to the GUI are planned. Most will be focused on making the GUI smaller, and more light weight.

Our website (www.playtell.us) has been updated with a newer build today. This build addresses many GUI issues, and scaling bugs. The game should also run fine now in 1920x1080 resolution, and anything under.

Expect a list of known bugs to be posted on our IndieDB forum within the next 24 hours, as well as many new screenshots of the game.

I would also like to remind everyone who finds a bug, that it is important that you report it to our bug forum. We really would appreciate the help!

Enjoy the game!

really enjoyed the game...very interesting idea :-)

I was wondering if you were considering adding a 'food level' component. I only say so because in my game i completely ignored food technology and just industrialised the whole world without any negative effects as far as I could tell..

Great question.

We are currently implementing a system that gives specific "stats" to certain regions. These stats can include food, population, fossil fuels, and a wide array of other things. They can also have sub classes, such as the amount of a specific food type, or the male to female ratio of a region.

These "stats" are affected by a large array of variables within the region. They can be changed by anything from the time of year, to the amount of power plants, and everything else in between. They also are affected by the surrounding regions.

An example would be the population of a region going up, and the amount of food for that region going down as a result. This would cause the player to need to speed up food production.

So to answer your question, Yes we are. It's just still in the de-bugging stages. You can expect this to begin to show as we implement it within the upcoming few weeks.

Thank for playing! And I'm glad you enjoyed it!
If you have any other questions, feel free to ask.

The Tellus team has been awfully quiet for far too long, so I wanted to reassure everyone that development continues. As you might imagine, student projects that go on for more than a semester or two often struggle with team changes, and all of our original leads have left the project over the last 6-8 months. That's what happens when people graduate and get "real jobs!"

Fortunately, we have a terrific new team who have been diligently working on improvements in all areas of the game. In the near future you can look forward to a new build with several enhancements to the UI, some great new game mechanics, an actual working tutorial, and much more!

Do you know the resource based economy(RBE)? Maybe it could give you good ideas for your game.

Thanks for the suggestion about RBE, damiandj90. We have an admittedly curious economic model for the game, and this is something we are working on refining. Some other, more rational ideas about economics can be found in the works of R. Buckminster Fuller and Robert Anton Wilson. One of my favorite ideas is Wilson's The RICH Economy.
