Alternate Ending
Successfully complete the game on any difficulty setting three times to hear alternate music during the ending sequence. |
Bad Stealth Change
Unlike the original Metal Gear Solid, in TTS while in stealth mode you cannot just walk through the infrared sensors. If you do, they will go off and alert the soldiers; or in the cargo area (exit from tank hanger to fight M1 tank) the gas will go off when you walk through. |
Bandanna
Successfully complete the game on any difficulty setting after not submitting to the torture. At the end, Meryl will be alive and find a Bandanna on the snowmobile. She will give you the bandanna. When equipped, the bandanna will allow unlimited ammunition on any weapon when selected. |
Black Screen During Hind D Battle
When the first part of the Hind D battle begins, when you have to go down the building with a rope, do not pick up the rope when you first go up the twenty seven flights of steps. When the intermission sequences on the roof are over and the Hind is flying around shooting at you, go back by the ladder and you will not be able to go down it. Leave that room and go back onto the roof. The screen will turn black, and the only way you can see what you are doing is by looking at the radar. If you lean against an object or go into first person view, then the screen will return until you move again. The screen also returns on if you go back into the room with the ladder. This might not happen every time you try it. |
Camera

Eternal Darkness Reference

Pick it up, open it, then zoom in on the contents to find her.Have a saved game file from Eternal Darkness on your memory card and Psycho Mantis will make a reference to that game prior to the Boss battle.

GameCube Hardware

Get Health During Torture
When starting the torture, just press A as usual. When the blue bar is empty, turn on auto-fire to get your health back up to full. If you use that feature from the start, the game will "know" and you will die anyway. |
Heat Signature
During the Psycho Mantis battle, the armor suits in the room have a heat signature when you are wearing the Thermal Goggles. There should be no heat signature since no one is inside the suits. |
Mario And Yoshi Reference
Look on one of the file cabinets in Otacon's office to find statues of Mario and Yoshi. Shoot the Mario statue to hear the classic "extra life" sound, and increase your health. Shooting the Yoshi statue does not do anything except make a sound. |

It does not function during Boss battles and at the caves, because the dogs will smell you. |

Tux
To get the Tux, you will need to get the Stealth Camo and the Bandanna. When you get both those items, you will wear a Tux instead of a stealth suit; also Meryl will wear it and Cyber Ninja will have a red exoskeleton. |
Underwater Gas Mask
If you put on your gas mask while under water, your O2 gauge will decrease slower, just like it would while in a room with gas. |
Wrong Steam Temperature
Put on your thermal goggles while in the room with the pipes that shoot out steam. The steam, which is supposed to be hot enough to burn you, shows up as something cold. |
Wrong Voice Actress Credit
In the credits for the voice actress, the game displays the character "Naomi Hunter" as voiced by "Jennifer Hale". This is not true. Jennifer Hale voices the character "Mei Ling", and "Naomi Hunter" is actually voiced by Carren Learning. You can confirm this by comparing the voices on Metal Gear Solid: The Twin Snakes and Metal Gear Solid 2: The Sons of Liberty on the PlayStation 2. |
Zone Of The Enders Reference
Look at one of the posters in Otacon's office to see the graphic from the front of the Zone of the Enders: The 2nd Runner box. |
