The Maxis Tetralogy combines all four episodes in the first Maxis Series into two epic volumes. Volume 1 begins with "MAXIS," as Jeffrey Blades is made an unwitting participant in the corruption and conspiracy of the ELEO. Then move on immediately to "The Spires," where the ancient and enigmatic artifacts become the center of a struggle for power between the planetary government and the world's largest conglomerate. Volume 2 picks up with the last chapter of Volume 1, as the humans of Maxis struggle to defend themselves against an intractable alien force in "Maxis: Invasion." Jeffrey Blades, must now use all of his cunning and guile as a military leader to forge a new destiny for his besieged home planet. With the help of his daughter, Kestra, his close advisor Kongming, and a host of others, they will fight on the land, in the cities, and even out in space, for their very existence. Unfortunately, as the first struggle ends, another begins in "Maxis: World at War." This time the people of Maxis face their greatest enemy; the one that tried to crush the new civilization in its infancy, the ones who seek to turn Maxis into salvation from their own battered home: The humans from Earth.
