Mercenary Wars is set in the not so distant future in a world where order and society as we know them are a thing of the past. The economies of the world have crashed and have been replaced with total chaos. New alliances have been forged and the world is now controlled by well-trained groups of mercenaries. Players must determine who to swear their allegiance to and fight side-by-side to the death, if necessary, in the quest to ensure becoming the new global powerhouse.
