In 2057, scientists invent a "mind-dubbing machine" that can digitize a human brain. Nonetheless, considering that "dubbing" kills the topic, the technology is banned-creating it very sought soon after in the black market place. A group of ruthless ninja mercenaries -- The Sons Of IGA, acquired the machine to produce a super-intelligent military thoughts. All IGA soldiers were forced to replace their consciousness with this new mind. Some refused...and had been destroyed. But dissent over the machine grew, and the STEEL KOGA faction was born. For six months, they warred fiercely against the IGAs but lost. The leader of the rebels, SK Panther, was captured and locked inside a mind-dubbing machine deep within Death Forest. The IGAs, dispatching their very best, lurk in wait to intercept the last, most harmful SK rebel attempting a rescue.
