Mars took its name from the Roman God of War because to those who first observed the planet in the night sky of Earth, it glinted with the ruddy shade of blood. But the naming seems to have been touched by the hand of prophecy, for on Mars, war still reigns supreme. Following the catastrophic economic and ecological damage done to it during the First Crusade of the Dark Legion, Capitol Megacorporation has been hard pressed to maintain the delicate terraforming machinery severely damaged during that black time millennia ago. With the onset of the Second Crusade, Capitol and all its other inhabitants find themselves embroiled in an all out battle for their very lives. Now, the might of the Capitolian Juggernaut is shaking off its lethargy and preparing to reclaim its title as the most powerful Megacorporation in the universe and prepares to go to any length to prove it. Mars, World at War is the first in a planetary series of supplements for the Warzone: Universe under Siege game. In this captivating sourcebook you will find a complete history of the taming and shaping of Mars, a study of its climate with optional new environmental rules, a political breakdown of Megacorporate activity both above and beneath Mercury, as well as new units and equipment for each army in the Warzone Universe. Also includes an extensive section on running campaigns in the Mutant Chronicles Universe, expanding on the basics outlined in the core book.
