Hi everyone!

My name is Ivan Grozev and I've been working as a game designer at Haemimont Games for more than six years now. I've been fan of Paradox Interactive's games for decades. I've enjoyed thousands of hours of Europa Universalis and Crusaders Kings, always striving to achieve the next world conquest, and I've always loved large scale, long-term games. There's a saying in the design team that we've made a game especially for me. Frankly, I've loved working on Surviving Mars since the start and I'm excited with my current position as the Lead Game Designer for this project.



Today, I have the honor to briefly introduce to you the second expansion of Surviving Mars, Green Planet.

So, how did it all start? The inevitable truth that surviving Mars' barren deserts would eventually lead to humanity changing the Red Planet has stuck with us since we started working on Surviving Mars over 2 years ago. Back then, we didn't know what the future of Mars would look like, but we did envision that one day we would add terraforming. The growing desire for more late game content among our fans made this vision more and more appealing, as terraforming an entire planet would be a gradual and painstaking process. Believe me, we strived to make it challenging but worthwhile!

In Green Planet, you'll be able to fully transform the Martian surface. Starting with endless, barren deserts and leading to frozen ice caps and fields of lichen, and finally ending with a planet covered with lush green forests and oceans. You'll be able to plant different types of vegetation all across your colony, dig artificial lakes and fill them with water that freezes or evaporates according to the average global temperature, decrease the severity of dust storms as atmosphere improves and watch Moisture Vaporators produce more because of oceans evaporating water into the atmosphere.

In order to do so, you need to achieve progress on four major terraforming parameters: Atmosphere, Temperature, Water, and Vegetation.



The Atmosphere parameter symbolizes the density and the content of the Martian atmosphere. At 100% Atmosphere terraforming progress, Mars has an Earth-like atmosphere and deep blue skies, capable of sustaining human breathing without artificial aid. There are several ways to improve this parameter, varying from mass production of greenhouse gases to melting the polar ice caps. Initially, it's easy to improve the atmosphere; however, its raising density means that more and more gases are lost due to Mars lack of a strong magnetic field. To continue the process, the need for magnetic shields in orbit and massive magnetic generators arises.

The Temperature parameter symbolizes the average planetary temperature. It's necessary for liquid water to exist on the surface of Mars and for more advanced plant life to survive the extreme Martian conditions. The increasing temperature creates conditions for the polar ice caps to melt and changes the existing ice fields into blue lakes, seas, and oceans. Higher average temperature also means that cold waves are shorter and less likely to occur.

The Water parameter symbolizes the amount of water accumulated in the atmosphere and in water bodies on the surface of the planet. Water is a major ingredient in the making of acidic and pure-water rains. It directly affects the output of Moisture Vaporators and is required for more advanced plant life to grow and spread.

The Vegetation parameter symbolizes the sustainability of plant life on the planet. Initially, plant life consists of adapted cyanobacteria and lichen but it will eventually form huge, continent-wide forests. This parameter directly affects the spreading of plants around your colony. On one side, it increases the likelihood that locally seeded plants will spread on their own. On the other side, it guarantees that, over time, seeds carried by the wind will grow in various locations on the map.



You're probably asking yourselves "How could I achieve all that?". You'll notice that Green Planet has added a new technology field, Terraforming, in your Research UI. The 20 new techs there are harder to research but will allow you to start terraforming whenever you feel ready for the challenge. To begin, just unlock the first building in the tech tree. You achieve terraforming progress by constructing and maintaining terraforming-related buildings, or by completing dedicated terraforming projects such as sending rockets to capture ice asteroids. We're going to talk more about these in the following dev diaries.

Speaking of which, next week on Thursday well have another dev diary all about the new buildings and wonders coming in Green Planet.
