Welcome to the Metal Gear (MSX) Walkthrough! This will walk you through the entire game and all boss fights.
The guide below was written based off the original game’s difficulty, but there are no difficulty requirements for Trophies/Achievements. This can be played on Easy.
This isn’t a traditional Trophy/Achievement guide, but the list is just about all story related Trophies/Achievements.
There are only two non story related Trophies/Achievements. One is for completing Boss Survival mode. The boss strategies are all explained here in the walkthrough. None of them are that difficult.
You will need to first beat the game in order to play through Boss Survival mode. You cannot die or kill any hostages during Boss Survival or else you’ll need to start over.
Make sure to pick up the Rations and ammo during each fight to have them for the later bosses.
The other is for reading the Screenplay Book. All you have to do is open the book and tab through all the way to the end.
When coming across items in the game, you can farm Rations and ammo. Enter a room that has Rations or ammo, pick it up and then exit the room. Re-enter the room and the items will respawn and you can pick them up again. You can repeat this until your inventory is full.

After the fight Card 8 will spawn. Free the hostages and pick up the card.
We are just about to the end of the game. Before proceeding, go stock up on Ammo, Rations and Plastic Explosives.
You can get some Rations from down in the basement maze. The Plastic Explosives can be found in the room below the level 7 door that you use to enter the scorpion desert.
When you’re ready to go, cross the scorpion desert again. Use the Compass.
Cross the desert, run by the two ambushes and ride the elevator down to the basement again.
Don’t forget about the traps in front of the elevator.
Exit the elevator go in the door on the right with Card 8. The camera guarding it won’t call for enemies. It’ll just shoot a laser at you. Just keep running and you’ll avoid the shot.
Rescue the hostage.
Exit the room and go through the bottom left exit.
Open the door with Card 8, equip the Gas Mask and then enter the doorway.
Enter the room and then go to the top left corner and plant Plastic Explosive to blow open the wall.
There is a trap in the next room. Don’t run up the center of the room.
The next room has gas and mines in it. Use the Mine Detector and quickly run through, or wear the Gas Mask and use the picture below.
Use Card 1 on the door in the top left.
There is no control panel in the room with the electrified floor. You’re going to just have to run and get across as fast as you can. Use a Ration before going.
Get through the door and then use a Ration. It’ll be time to take down Metal Gear.
In order to beat Metal Gear, you’re going to have to plant the Plastic Explosives in front of its feet in a certain order.
The order is:
R – R – L – R – L – L – R – L – L – R – R – L – R – L – R – R
Metal Gear won’t attack you. It’ll just be the cameras going back and forth behind it that you need to dodge.
After Metal Gear is defeated, there will be a count down clock running.
Exit to the left.
As soon as you enter the next room, you’ll be in a fight against Big Boss.
You’re going to have to use your Rocket Launcher to beat him.
Get behind cover and stay there. That’ll get Big Boss to stop moving around. Pop out of cover, shoot a rocket and then get back in cover.
He should step into the way of the rocket. Repeat that until the fight is over.
When you enter the next room, open your inventory and use the Cigarettes. This will add some time to the timer. You have to actually select them to use them. They’ll disappear from your inventory when used.
Climb up the ladder on the left.
Climb all the way to the top and you will have beaten the game.
If you’re looking for the Platinum Trophy, Boss Survival mode is now unlocked.
Go beat that to finish off all of the Trophies/Achievements for the original Metal Gear.
You cannot die or kill any hostages during Boss Survival or else you’ll need to start over. Make sure to pick up the Rations and ammo during each fight to have them for the later bosses.
