Metal Gear Solid Cheats

When you reach the title screen, push any of the directions on the D-Pad to be able to get different colors for the background graphics.

To view Otacon's Ending instead of Meryl's ending after completing the game, submit to Ocelot's torture after being captured.

Resist Ocelet's torture to see a happy ending where everyone lives. You can use a turbo controller.

If you don't have the mine detector, but want to cross a minefield without having to worry about blowing up, just go up to the area where you believe mines are and crawl across the ground. Not only will you be unharmed, but you will also receive any claymore mines that you crawl over!

Make the boss fight with Psycho Mantis much easier by switching your controller to port 2 when the message HIDEO appears on your screen. If you do it correctly, Psycho Mantis will be unable to read your thoughts making the fight much easier.

When you're in the cave area with Meryl, hit her and quickly equip a cardboard box. She'll order a wolf to attack you, but if you're in a box, a wolf will pee on it instead. Now whenever that box is equipped the wolves will no longer attack you.
