Nuke Bldg 1
After the fight, you’ll automatically be in the Nuke Storage Building 1. Your health, Rations and ammo capacities will increase a bit. You will also now have the LV. 3 Card.
There is a Ration on the left side at the very end of the catwalk.
Run to the big door and crawl underneath it.
On the other side, you’ll receive a call from Campbell telling you that you cannot use weapons in this room. You can still use Chaff Grenades, however.
There is another fast travel truck in this room straight ahead from where you crawled in. We don’t need it right now, and there is nothing inside of it.
There is some Fa-mas ammo to the right of the truck, but it can be tricky to get without being seen as there are guards patrolling as well as a camera near by. If you’re spotted in this room, you’ll be locked in and gas will be deployed. We don’t have a gas mask yet, so that would all but guarantee a death.
So for now, we are gonna just get through this room and on to the next.
After the Codec call about your weapons, go left and then quickly go up between the first row of nukes. There is an enemy nearby headed your way, so be fast.
At the top, go left. There are Chaff Grenades on your path you can grab here. Grab them and head down. There are also some Grenades across from the base of the stairs in the bottom left corner of the first floor.
Go up the stairs. Watch out for a guard up here patrolling. When he heads the opposite way, go to the elevator and take it down to B1.
Rescue Otacon
Exit the elevator and equip the Lv. 3 Card. Enter the main room across from the elevator. There is an enemy using the bathroom nearby. If you’re fast enough, you can get in and out of here before he joins the other guard on patrol. Or, you can go in the bathroom and take him out.
There are several offices inside of the main room, but we only have access to one at the moment. There will be another guard in the main room that you can either sneak around or kill.
Go to the first room on the right side and pick up the Nikita Launcher as well as the ammo for it.
Exit the main room and get back to the elevator. Ride it down to B2.
Exit the elevator and enter the two doors ahead of you.
Do not step out onto the grating. The floor is electrified. In addition to that, the area is full of gas. Pay attention to your O2 meter. If it gets too low, exit the air to refill it.
Equip the Nikita, and fire a missile down the hallway.
You’ll be able to control the missile that you fire with the Nikita.
While the missile is flying, hold 
/ 
/ 
to enter a first person view of the missile.
You’re going to need to maneuver it to the electric panel to disable the electrified floor.
At the end of the hallway, turn the missile right.
In the next room, turn the missile right and fly it to the back of the room.
The cameras in this area can shoot and destroy your Nikita missile. You can fly the missile into the wall under a camera to destroy them if needed.
At the back of this room, turn the missile slight left and fly it in-between a sliding glass door.
As soon as you get through the sliding door, turn right and then fly into the electrical panel on the wall.
With the electrical box destroyed, the floor will be safe to walk on.
Go down to the third room on the right of the first hallway. Throw a Chaff Grenade and go inside to find a Gas Mask.
There are other items in this area you can grab if you’d like, but we don’t have access to all of the rooms yet. Everything else that can be found here at this time is listed below.
- Ration
- C4
- Grenades
- Nikita Missiles
- Chaff Grenades
- Ration
If you do go get those, make sure to wear the Gas Mask and use Chaff to avoid cameras.
When you’re ready, exit through the door on the right of the main hallway guarded by a camera.
Cyborg Ninja Boss Fight
Make your way through the next short hallway littered with dead soldiers.
As you enter the lab, it’ll be time to fight the Cyborg Ninja.
During this fight, you’re going to need to use your melee attacks. Punch, punch, kick. Your weapons will not work against him. You can use Chaff Grenades, but those are only good for a single combo. Afterwards, he’ll be invulnerable until the Chaff wears off.
This fight will be broken up into a few phases.
First, he’ll be near you with his sword out. Two kick melee combos will be enough to end this phase. He’ll put away his sword.
The next phase will be the longest one. When he gets near you, he’ll combo some lunging kicks together. As he kicks, he’ll be moving toward you.
So, keep moving and get out of his way. If you’re quick, you can land a combo of your own on him after he finishes his kick attack. If you get too close while he is still moving, you’ll take damage.
Every now and then, he’ll mix in a jump attack. He will jump up inn the air and hang for just a quick second and then come straight down. There will be a shockwave where he lands, so makes to get out of the way. You can land a combo on him when he lands.
After this phase, he’ll use his stealth camo. This makes him somewhat invisible. He won’t come after you, instead, he’ll be standing still somewhere in the room and you’ll need to find him.
It is possible to see him normally as the area becomes distorted, but you can use your Thermal Goggles to instantly spot him. When you do see him, run up to him and land a combo.
After this phase, he’ll slowly walk toward you. As you get close, he’ll very quickly disappear and then reappear throwing a punch. Get close to him to bait him into throwing a punch and run away from him. After the throws the punch, there will be a window where you can hit him with a combo.
The final phase will work a little differently. He will be surrounded by an electronic sphere. He won’t come after you, but the sphere will pulse which will damage you if you’re too close. So for this, just go ahead and use your Fa-mas to finish him off from a distance.
After that, the fight will be over and you’ll be introduced to Otacon.
Finding Meryl
After the fight, your health will increase and you will now have the Lv. 4 Card.
Exit this area the way you came in. When you get back to the gas filled hallway, equip your Gas Mask and run straight across to the other side. This will be the area where you shot the Nikita missile.
Drop a Chaff Grenade.
Go up to the last door on the right and equip your Lv. 4 Card. Enter the office and pick up the Night Vision Goggles. This is near the electrical box from earlier.
Exit that door an return to the elevator you used to come here originally.
Ride it up to B1.
From the elevator, enter the main room where the Nikita was found. As soon as you enter, Meryl will be disguised as Genome Soldier.
She’ll be on the left side of the screen. Run into her vision cone and she’ll spot you. She’ll then run to the bathroom to the right of the elevator you just took. Follow her into the last stall to initiate the next cutscene.
Before leaving the women’s bathroom, take a picture of the mirrors above the sinks and save the photo.
If you’re not sure what guard Meryl is, you can look through first person at the way the guards are walking. Meryl will have a distinct walking animation.
Psycho Mantis
After the scene with Meryl in the bathroom, exit and go up the hallway to the left of the elevator. Go through the next two doors and it’ll be time for the next boss fight.
In the original version of Metal Gear Solid, you would have to unplug your controller and plug it into the second controller port.
Obviously, that cannot be done on modern consoles. The Master Collection does however come with a built in digital controller system.
In order to beat Psycho Mantis, you’re going to have to use the digital controller port system to switch over to the second port. This will prevent Psycho Mantis from “reading your mind.” He’ll dodge your attack every time you try to hit him if you don’t switch ports.
With that out of the way, it’ll be time to actually fight him.
His attacks are easily avoided just by moving out of the way. When he uses stealth, you can use Thermal Goggles to track and follow him.
When he takes enough damage, he’ll start levitating things around the room. Lay down prone to avoid the objects he throws at you.
