Armored Core: Verdict Day (Girls' Frontline)

World War Three is the global conflict that engulfed mankind from 2045 to 2050 or 2051 following the First Beilan Island Incident.[2][3][4] Along with the Collapse Fluid clouds, the war destroyed most habitable lands as well as many nations. The political face of mankind was changed to a completely new state as superpowers were brought to their knees, eventually leading to the emergence of two superpowers in the aftermath: the Union of Rossartrism Nations Coalition and the Antarctic Union.

Verdict Day is set around 100 years after the events of Armored Core V. Following The Raven's victory over Exusia, the contamination that isolated humanity had begun to subside, allowing humans to return to more of the world. The discovery of high-tech Towers, once hidden by the contamination, ignited a new war--known as the Verdict War--between several different factions. Adding to the conflict is a mysterious group known as the Reaper Squad, as well as the usage of Unmanned Armored Cores called UNACs. The game follows the story of an unnamed AC pilot, generally indicated as The Raven, who accepts assignments on behalf of various factions, encountering numerous mercenaries in battle, before entering into conflict with the Reaper Squad and the Foundation.
