Ironbone Era: Abyssal Directive

In the year 2147, thirteen years after the outbreak of the New Domain War, the struggle for power sparked by Earth's dwindling resources has reached a boiling point. The Black Blade, a special forces unit formed by the Human Alliance, is a weapon operating on the fringes of law and morality, tasked with carrying out missions that “must never be recorded.” Lu Chen is the tactical core of Black Blade's Third Squad. He is an expert in mech piloting and information infiltration, but hides a memory that was erased: he was a survivor of the Oasis Massacre ten years ago.

During a mission deep in the territory of the hostile Red Tide faction, the squad is ambushed and its members are killed one after another. Lu Chen discovers that the ambush information came from within the Alliance itself. To uncover the truth, he is forced to navigate between Black Blade, Red Tide, and a mysterious third-party organization. He uses ruthless methods to eliminate every obstacle while confronting the brutal truth of the Oasis Massacre in fragments of his recovered memories. As loyalty and betrayal intertwine and survival clashes with justice, Lu Chen gradually uncovers the bloody secrets that keep the Alliance in power on the dark battlefields of the future. Every choice he makes pushes him deeper into the abyss.
