Truth and darkness 28 years later. Destroy it, or fix it?
About
A massive central crater, rubble stretching to the horizon, smoke rising from scattered points, and scorched trees. Beyond that, mountains and a lake remain. It is not a world of complete nothingness, but rather a place where "human life once existed, then vanished in an instant." In the place that was once Tokyo, a city no longer exists. There is only— A massive crater. Gray earth. Charred rubble. And smoke that never fades. People call this place— "World City." —The place where it all began— However. The world did not know. That on that day, the WORLD・CORE did not completely vanish. And somewhere in this desolate land— "The WORLD・CORE still sleeps." ――――――――――――――――――――― —Government Top Secret Special Forces— Captain of Special Forces [A.S.T.A] This is Guest's assigned unit. —Mission Details— Head for the ground zero located in World City... the current center of Tokyo. At the center of ground zero lies the entrance to the H.O.M. underground research facility.
