In the twilight of Earth's great civilizations, we were chosen to venture to the stars in search of a new home. But we did not travel alone. As we slept, behind us streaked messages from Earth. Their dream that we would not let the light of humanity extinguish. When we awoke we listened to words spoken centuries ago. As we gazed across the vast space and time that separated us, we hoped that Earth still lived and that the words were not the echoes of ghosts.

The Design Pillars of Echoes of Earth 1. Remember Earth Earth's commitment did not end when the seedships were launched. The messages of the Signal streaked across space, ready to decode and read upon arrival at the new world. Earth channeled much of its dwindling resources into aiding your survival, and the time will come to repay that generosity. When the messages from Earth grow desperate, what will you do? Will you take the extra step to start sending help back - even if it may not be enough to save Earth? 2. Play the Map Never before has the map been so critical in the choices you will face. What terrain and resources are nearby will determine what improvements you can make and what buildings are available. Specializing your cities to take advantage of the things they are uniquely suited to do will be key in growing an effective colony. Your technology and diplomatic trait choices will be shaped by what parts of your colony you want to benefit. 3. Struggle to Survive Life is not easy on the new world. Energy will be scarce, Health will be a concern throughout the game and orbital units will require effort to sustain. Many yields are harder to come by. If your colony lacks for certain resources you will have to struggle to preserve with the constraint. The planet does not welcome you and survival will require foresight and cunning. 4. Dynamic Decision Making No two games of Echoes of Earth will play out the same. From the moment you make planet fall you will need to form your strategy within the tools you have available. You will not be able to follow the same steps in every game. You will need to utilize your colony's strengths while mitigating its weaknesses. Even as your colony establishes itself on the new world its Affinity will shape its play style. Each Affinity has unique improvements, buildings and technologies that give it a fundamentally different play style than the alternatives. What is new in Echoes of Earth Completely redone tech web Completely redone buildings and building quests New early and mid-game quest chains New Affinity point economy (less old quest and tech, more varied ways to get points) A new orbital system A new Health system A new Trade Route system A new Energy economy For more information on the new systems go to the official guide.
