At the end of the ED campaign Falkner is betrayed by his superiors, who fear his idealism, and imprisoned. Upon reaching it an insectoid alien race is found, which then becomes the primary antagonist. Falkner completes various missions for his (obviously unethical) ED superiors, largely against the LC, until he is sent to investigate a biological research operation that has gone silent. In Earth 2160 the player initially takes the perspective of Major Michael Falkner of the ED forces. Both the ED and LC set about the difficult and lengthy task of terraforming Mars independently of one another, and also set up outposts on the outer planets and moons. All three factions succeeded and sent ships to Mars, however the UCS colony ship inexplicably disappeared en route. In Earth 2150 the three factions of the United Civilised States (UCS), the Eurasian Dynasty (ED) and the Lunar Corporation (LC) raced to build starships and evacuate the Earth before it became uninhabitable.
The game continues the dystopic themes of the previous Earth games, and is set in numerous locales throughout the solar system. It was also released on Valve Corporation's Steam platform in April 2006, and later from Good Old Games in 2009. The release of the game was staggered, originally published in Russia, Germany and Poland in June 2005, it was then released in the rest of Europe in September 2005 with North America receiving the latest release of the game November 2005.
Earth 2160 is a real time strategy (RTS) computer game, the third in the "Earth" series and developed by Reality Pump studios.
