Crimson Guard

In 2045, the "Crimson Calamity" swept across the globe—a mysterious red fog of unknown origin enveloped cities, causing those exposed to gradually suffer mental collapse and grotesque mutations. Human society collapsed within months. The player assumes the role of "Zero" (codename), who awakens in an abandoned "Sector 7" military base with no memory, bonded solely to a specialized mech named "Crimson Oath." This mech is the ultimate creation of the old world's "Emotional Resonance Technology," with its performance fluctuating in real-time based on the pilot's emotional state.
