Faced with an insurmountable threat on Earth and in a desperate attempt to find a new refuge, the people remaining on the planet embark on an expedition to the Pegasus Galaxy, but there they find themselves in the midst of an interstellar war, which they accidentally started. Players lead one of humanity's fleets and set off into the unknown in a fight for survival. In the game you can develop your own units and become a skilled diplomat or economist. There is also a story campaign in which there is no classic division between good and evil, and all decisions made will have consequences.
