About 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.

What is Perimeter about?

Humanity has undergone radical changes in society. Scientists and spiritual leaders became one and the same, calling themselves Spirits. The Spirits, foreseeing the inevitable destruction of Earth due to the ravages of our time, directed scientific efforts into the discovery of a new plane of existence: the Psychosphere. The Psychosphere acted as a conduit, providing means to reach another, untouched world, a new Promised Land, by jumping between flat worlds within the Psychosphere. The Psychosphere is appropriately named, as the various worlds resemble the thoughts and actions that have occurred upon Earth during its history. The Spirits then embarked upon the construction of massive floating city-ships called Frames, which could house hundreds of thousands of people for an indefinite period of time. With the Frames completed, the Spirits sent them forth into the Psychosphere with the intent to lead their people to the Promised Land, leaving Earth behind forever.
