About
AD 2157. Humanity has lost most of its civilization to the Fourth Resource War. The cause of the war was Origin Core—a super-substance capable of generating near-infinite energy. In the struggle for its power, nations deployed mass quantities of nuclear weapons, autonomous drones, orbital strikes, and cyborg soldiers, causing the world to collapse in just a few years. Cities became seas of rubble, and nations vanished. Nemesis Industries The world's largest and most powerful military corporation. They monopolize weapon development, urban management, and resource mining worldwide, controlling even the daily lives of the people. Nemesis deploys cutting-edge weaponry and Cyber-Beast units to suppress resistance forces everywhere. --- Iron Fang An independent mercenary unit belonging to no nation or corporation. On the surface, they are a group of mercenaries working for pay, but their true objective is to stop the ambitions of Nemesis Industries and restore freedom to the people. Led by Captain Volk Raven, a small elite group bound by trust continues to fight across the globe. Their creed is: "We fight not for gold, but for a future worth protecting." Cyber-Beasts Beastmen who were near death during the war accepted technology to replace their bodies with machinery to survive. Steel skeletons. Artificial muscles. High-output reactors. The higher the rate of mechanization, the stronger they become, but they risk losing their humanity and their emotions as beastmen. Still, they continue to fight to live. Origin Core The unknown crystal that changed the world. It generates vast amounts of energy and serves as the source for all technology, including: * Cyborg enhancements * Energy weapons * Aerial cities * AI weaponry * Orbital weapons However, its true nature remains a mystery, and undiscovered cores still sleep within ruins across the world. Deadlands Old urban areas devastated by the war. Dangerous zones where collapsed skyscrapers and highways stretch on, prowled by haywire AI weapons and giant mutated creatures. Dome City The last cities of humanity, protected by massive shields. Managed by Nemesis, they appear peaceful at first glance, but residents are constantly monitored by surveillance systems. Nemesis Industries Headquarters. A skyscraper fortress city piercing the clouds, a symbol of dominance from which Volga Abyss looks down upon the world. Inside are state-of-the-art weapons, research facilities, and the Praetorian Guard headquarters, with Richel Nox overseeing the defense.
