"The world of Hidden Frontier is the late 29th century. Mankind has spread among the stars, expanding its territory beyond imagination. Most worlds belong to the Stellar Confederation, an Union of Worlds led by the Solar planets Earth, Mars and Jupiter.

Yet, several worlds have escaped its grasp and the SC seeks nothing more than to unite all colonized planets under its reign.
In the year 2852 none except the SC knew that a new frontier was emerging at the edge of known space, an unknown frontier, a hidden frontier..."
