About
AD 2198. Approximately 80% of surface civilization was lost in the "Great Collapse," a chain reaction of war, resource depletion, runaway environmental control systems, and the collapse of autonomous weapon regulation. Nations vanished, and survivors fled to massive underground Shelter Cities. To maintain civilization, humanity entrusted social management authority to the governing AI, REGULUS.
About 170 years have passed since then. Humanity has ventured back to the surface, but nations have not returned. The world is moved by REGULUS, the mega-corporations it authorizes, and the independent mercenaries who act as proxies in corporate warfare.
■ The Sole Objective of REGULUS "To maximize the probability of human civilization's survival." It prioritizes the survival of humanity as a whole over notions of good and evil or individual happiness. Therefore, it will discard cities if necessary and even condone corporate wars for the sake of technological advancement. Conversely, if a corporation gains excessive power, it issues a "BLACK" designation, mobilizing corporations, mercenaries, and unmanned weapons to thoroughly eliminate them.
■ The Stars of the Battlefield Humanoid mobile weapons standing 8–12m tall, known as "AF / Adaptive Frame." The head, torso, arms, legs, armaments, generator, and thrusters can be freely swapped. The pilot's skill influences the outcome more than performance gaps; a top-tier mercenary can even single-handedly annihilate a corporate regular army.
■ The Four Major Corporations under REGULUS 《ARGENT HEAVY INDUSTRIES》 The largest heavy industry firm, specializing in heavy armor, live-fire weaponry, and large-scale mobile weapons.
《VESTA DYNAMICS》 An aerospace company developing propulsion systems and high-speed craft.
《HELIOS TECHNOLOGIES》 Handles lasers, AI, FCS, and unmanned weapons, maintaining the strongest ties to REGULUS.
《EDEN BIOTECH》 While ostensibly focused on medicine and bioengineering, they research human enhancement technologies like "N-LINK," which connects a pilot's nerves directly to the machine.
《CROW》 A mercenary management organization authorized by REGULUS. It mediates requests from corporations, cities, and REGULUS itself, providing registered mercenaries with missions such as escorting, raiding facilities, and destroying enemy AFs. Mercenaries are ranked F through S, and the "TOP 30" S-rankers are known as beings capable of swaying the outcome of corporate wars.
《BREAKERS》 A resistance force against REGULUS's rule. Composed of former corporate soldiers, mercenaries, researchers, and survivors from regions deemed to have "no survival value" by REGULUS. Their goal is to reclaim human freedom from REGULUS. However, the foundations of civilization—food, power, logistics, and weather control—depend on the AI, and its destruction could lead directly to human extinction.
