2212 AD. As humans advance into the universe, a star rich in minerals is found just 15,000 km from main hub Alpha Centauri. It gets name "New Hope" and soon becomes a dream destination for all immigrants.

But one day in 2214 this star gets ambushed and captured by an unknown alien civilization "Phochum Central Unified Holy Empire".
The Allied Forces organize immediately send forces, but face a total defeat due to the huge gap in technology level. Soon Alpha Centauri gets captured as well, and humanity habitat narrows down to Solar system. Pluto becomes a base for counterattack, but only admiral experience prevents total defeat. Enemy forces approach the lunar base and occasionally hit important objects on the Earth with missiles when the latest generation super-dreadnought space battleship finally gets ready for battle.

December 3, 2215 becomes the Judgement day for humanity led by our brave admiral.
