Perimeter + Perimeter: Emperor's Testament

Perimeter
Perimeter is an innovative Real-Time-Strategy game that pits players against each other or AI opponents in a life and death struggle to seize territory and establish critical protective “perimeters.” Players will be introduced to the game’s unique “terraforming” feature, allowing them to move, build, construct and destroy the map environment. Set in a future where the Exodus civilization has abandoned the dying Earth, the game offers a well-balanced combination of new terraforming principles and territorial wars with traditional strategy elements.

Perimeter: Emperor's Testament
In the near future a new Exodus begins, the remnants of human civilization have to leave the perishing Earth and start traveling into the Psychosphere. The ones who call themselves the Spirits - new pastors of the human race, believe that a new planet, suitable for living, will be found in the Psychosphere. Colossal towns-arks, carrying hundreds of colonists, have been traveling for centuries through hostile worlds of Psychosphere under the guidance of Spirits. Their destination was the New Earth that was to replace their old home. All passed worlds have been connected by portals, that is how the Chain of Worlds has been created.
