Chapter 5

The 20th floor is a place big enough to hold a Metal Gear. But it isn't their. Hydro is standing on a raised platform that circles the top of the floor. In the middle of it is a pillar which goes from the floor to the ceiling. It is a huge drop from the balcony to the bottom. At the back is a freight elevator. If the Metal Gear was once stored here, it would have been easy to get it out.

Hydro is about to contact Snake when Cobra calls him from behind. Oxygen and The Professor are with him, together with the same hostage from Granda. Cobra threatens to kill her if he doesn't do what he says. Hydro agrees. Cobra tells him to send a message to Frank Scott. Either hand over $20 billion in three hours or a nuclear missile will be launched in a location other than the U.S. The U.S. would then be framed for the attack and a nuclear war would start. Hydro tells Scott and then asks Cobra where the Metal Gear is. Cobra tells him it is on the surface ready to be launch the missile. Ocelot, with ten other men comes up from behind Hydro. Cobra tells him his times nearly up and soon everyone will know about his wonderful creation, Metal Gear N. NRAIN doesn't want the money. It's just a cover up. The missile will be launched anyway. Ocelot forces Hydro down onto his knees.

The Professor then tells of the Metal Gear. After being sacked from the SAS after illegal arms sales, a person was sent to kill him because he knew top secret information about a corrupt Prime Minister. The Professor managed to escape from the assassin and decided to get revenge on the British government. He published the details and the Prime Minister was imprisoned. The Professor fled to Russia where he met Revolver Ocelot and Gun. Soon after he joined NRAIN and began work on his greatest design, Metal Gear N. Two years later, it was finished, NRAIN approved and it began to be built in the base you are in now.

Hydro was still on his knees as The Professor continued. He was still angry with how the SAS tried to kill him and so decided to use one of their most secret information. The missile that will be launched isn't nuclear. It's biological. Inside is a Genetically Modified virus called Naurainaus. NRAIN for short. The SAS had discovered it in a laboratory in an undisclosed country. The Professor had been working on it before he had been kicked out. Before he left, he took a sample of it. It is impossible to cure as when a person is infected, they die within days. The virus attacks the brain. The missile is also destructive. After the main impact, several hundred cluster bombs are released and are spread up to 100 miles in each direction. Within a day, a reasonable sized country would be 100% affected by NRAIN.

Cobra then gets a handgun out and points it at Oxygen. He tells him that he should have listened to Snake. He is about to shoot him when someone shoots The professor in the back. Using it as a distraction, Hydro gets his SOCUM out, turns round and shoots Ocelot in the leg. He also shoots several of the guards. Oxygen also breaks free, hits Cobra to the ground and then runs for it out of the room. The mysterious sniper kills the rest of the guards. In all of the confusion, Hydro had been shot in the leg.

After the smoke from the guns had cleared, Hydro, now on the floor, looks around him. Cobra is unconscious whereas the hostage is hiding in a ball. Hydro looks up and sees Snake with a PSG1. Hydro nods in appreciation. Cobra wakes up. Ocelot screams in pain. Cobra tells him that the mission was planned from the start. The disk was easy to hack into because he wanted Snake to be come and be killed for revenge. Daisy was carrying Cobra's baby. He orders to hostage to run off and she does. Cobra tells him that now both of them will die. A noise comes from below. Nitro is down there. He orders Hydro to come down or he will destroy the complex like he did in Granda. Hydro uses a ration and then jumps down. He sees that a bomb is placed on the pillar. Nitro states that if the bomb goes off, the whole facility will fall on top of them. He then sets a 5 minute timer and tells Hydro that they will fight until the 5 minutes are up. If Nitro isn't dead, he will destroy the complex after escaping killing everybody inside it. Nitro is a strong fighter and Hydro has to use grenades to harm him. When Nitro is growing weak, he uses a stun grenade to stun Hydro and then runs. When Hydro regains consciousness, the bomb goes off and the building collapses. Darkness.
