All for All

Humanity has won a great victory, liberating their homeworld from the alien Pashtali and convincing many of the alien Great Powers that Earth is much more than a vassal state of a decaying empire, easy meat for the first invader who comes along.  But the war is far from over.  The Pashtali are gathering their forces, closing down their border wars with smaller powers while the greater ones sit on the sidelines, readying their navy for a final confrontation with Earth.  The end cannot be long delayed. There is one hope left.  Allying themselves with the other smaller powers, the Solar Navy sets off on a final desperate campaign to break the aliens once and for all, or lose everything on the final throw of the dice.
