Nuclear Warhead Storage Building | Fourth act - Alaska MGS4:GotP Guide
Last update: 11 May 2016
Run down and you will find yourself in the warhead storage room. Get to the gates and try to open it [A], but after the Otacon you should know, that you have to get to the office to do so. He will give you the code - 48273. There is also the truck [B] and the elevator [C] inside the room.
Jump onto the truck and pick up the rocket launcher. Then go upstairs and call the elevator.
When you get down - go forward, to the end of the corridor, and turn left. The cutscene would be triggered. If you input the code Otacon gave you incorrectly - Snake psyche would lower.
When Otacon finishes his job get back to the elevator. Unfortunately, the way is blocked by the patrolling Gekko. When it goes to the end o the corridor - go to the desk. Crawl underneath it and pick up all the items you find.
Thanks to this you should get to the elevator But you have to still watch out for the Gekko, now to your right.
Call the elevator and get to the top floor. Go to the closed gates. You should see a cutscene showing MG trying to open it.
It's time for some action. The Gekko is not so dumb and is also able to use the elevator. Show yourself to him and start circling around the rockets.
First of all - don't let it get to the MG. Just as soon as the Gekko would stop chasing you - shoot at it. Probably you would have to play a few times a cat and mouse game with it, till the MG would unlock the gates. When the gates are open - pass by the Gekko and get outside.
