Metal Gear Solid: The Shadow Moses Incident

Warhead Storage

Entering into Dr. Emmerich's office, the Cyborg Ninja appeared once again and confronted Snake. Confused as to how the Ninja seemed to remember him, and finding his fighting style familiar, Snake defeated the Ninja, before he went vanished again. Snake realized the Ninja was Gray Fox, his old war buddy whom he had killed in Zanzibar Land. Snake later revealed his discovery to Campbell, who was initially in disbelief until Naomi confirmed this as the truth. She explained that Gray Fox had been used for gene therapy experiments, led by FOXHOUND's former chief of medical staff Dr. Clark, who had died in a lab explosion two years prior. Campbell had been unaware of this, as it had happened shortly after his retirement from the unit; Naomi only knew about it because she had stumbled upon it when she joined FOXHOUND. She added that Dr. Clark had recovered the body of a soldier after the fall of Zanzibar Land, and revived him. He had then been outfitted with a prototype exoskeleton, treated with drugs, and experimented upon for four years, leading to the creation of the Genome Soldiers. Campbell was sickened by this, while Snake asked Naomi as to why she had failed to tell them sooner. She claimed that it was confidential information, but Snake suspected that there was more to it than she was letting on. When asked by Campbell as to what happened to Gray Fox afterwards, Naomi stated that he had died in the same lab explosion that killed Dr. Clark, at least according to reports. The Ninja's behavior led Snake to speculate that Gray Fox didn't even know his own identity, and that the only reason that he had lived on was for a fight to the death with Snake. Rescuing Dr. Emmerich, who informed Snake he had developed Metal Gear REX, with no knowledge that it was to be nuclear-equipped. He believed that REX was intended for provide Theater Missile Defense against nuclear weapons. Dr. Emmerich informed Snake that REX's armament was handled by a separate department (in order to keep him in the dark) and that REX's rail gun (based on the rail gun for the SDI) was miniaturized for REX by a joint venture between ArmsTech and Livermore National Labs. Livermore Labs also developed an experimental nuclear weapon for REX. Finally, Emmerich warned Snake that if the PAL override keys didn't work, he would have no choice but to destroy REX. Snake also briefly expressed some concern for Dr. Emmerich, due to his experience of Anderson and Baker dying from a heart attack shortly after telling him everything they knew.
