Metal Gear Solid: Peace Walker

Prerelease Info

Unused Content#

Metal Gear AC!D Models#

To do: Show image of the model and test map.

There is a model of Snake from Metal Gear Acid 2, along with a test map of a small walking area. There is no known way to access this in-game, but these models have been extracted from the game. This was likely a placeholder from early in development.

Regional Differences#

To do: Comparison screenshots for the replaced items, as well as script comparisons.

Product Placement#

The Japanese version features in-game items based on licensed real-life products. These consist of recovery items based on food and beverages (such as Doritos and Mountain Dew), as well as magazines based on actual publications. In the international versions, these were replaced by generic or fictionalized equivalents. The Japanese version also features t-shirt designs based on these products and other collaborations, which could only be unlocked by logging into a Japanese PSN account and inputting certain passwords in the Extras menu.

Japanese Exclusive DLCs#

The Japanese version also has more exclusive DLC, such as additional t-shirt designs based on collaborations with Monster Hunter and the manga Arakawa Under the Bridge, as well as alternate voice sets for the A.I. weapons that are based on regional accents.

Torture Sequence#

Watch on YouTubeMain Ops Mission 20, "Torture Chamber Escape" features a torture sequence where Big Boss is tortured by Dr. Strangelove using lightning rods. Similar to the original Metal Gear Solid, the player must rapid tap the Triangle button to survive.

However, in the Japanese version, the sequence is altered where instead of lightning rods, Strangelove uses "laughing rods," which causes Big Boss to...have fits of uncontrollable laughter. Later conversations and scenes that reference this sequence were also changed to reflect this "alternative" method of torture. This change was likely done to get a lower CERO rating for Japan, since Peace Walker was targeted towards a younger audience compared to other games in the series.

Script Changes#

Some parts of the script in the Japanese version were changed or removed in the English version.

• In the briefing tape for the Naked camo, Miller expresses his desire to go skydiving naked.
• There are briefing tapes for some of the aforementioned licensed items.

Revisional Differences#

PSP v1.01#

• First release.

PSP v2.0#

• Added Transfarring capabilities.
• Added a disclaimer that appears at startup regarding MSF:

"The characters of this game referred to as Militaires Sans Frontières, MSF or Soldiers Without Borders are fictional: they are not in any way linked to or inspired from the non-profit organization Médecins Sans Frontières, MSF or Doctors Without Borders."

HD Remaster#

To do: This is a basic list to start, please expand if there's more changes. Include comparison screenshots where applicable. Also, see if any other cutscenes have dialogue changes.

In 2011, the game received an HD remaster for Xbox 360 and PlayStation 3.

• The control scheme was reconfigured to accommodate the extra shoulder buttons and right analog stick of the PS3/360 controllers. Voiced dialogue involving control explanations was revised.
• The controller's vibration function is supported during gameplay and cutscenes.
• The frame rate in gameplay and in-engine cutscenes was increased from the 20 FPS of the PSP version to 60 FPS.
• The missions and multiplayer battles support online play in place of the Ad-Hoc functionality of the PSP version.
• The feature for soldier recruitment via Wi-Fi scanning was removed.
• The Internet functionality for Downloadable Content and VOCALOID features were removed. The DLC was included in the HD version, except for any related to the VOCALOID features.
• The PS3 version supports "Transfarring", which allows the player to transfer save data between this version and the PSP version. Consequently, this could allow the player to transfer a completed save file from the PSP version and effectively have a "finished" save file on PS3. However, this doesn't unlock trophies, as that would require a save file to be started from the beginning on the PS3.
• Interestingly, the font for the menu text and subtitles differs between the PS3 and 360 versions. The PS3 version uses a font similar to the XMB's default font while the 360 version uses an Arial-esque font.
• Even more interestingly, some of the loading screens are different in the Xbox 360 version. In addition to adding "Loading..." under the peace icon, certain loading screens will display one of the game's characters and a quote for that character.
• Some cutscenes have revised dialogue. The voice acting in these scenes was revised to reflect these changes, but the subtitles and speech balloons were not.
  • In Main Ops Mission 5 "Rescue Chico", the line "Treasure your memories, Chico. No matter what happens, keep them safe." was changed to "He's gone, but there's one thing you don't ever leave behind-- your memories. Keep them safe."
  • In Main Ops Mission "Peace Walker Battle 2", the cutscene that plays after the battle with Peace Walker has two lines of dialogue changed: Snake's demands to call the Pentagon were changed to refer to NORAD instead.

Master Collection Vol. 2#

This needs some investigation. Discuss ideas and findings on the talk page. Specifically: See if anything else has changed. This is just to start.

The Xbox 360 version of the HD Edition was used as a base for the 2026 re-release included in Master Collection Vol. 2. (I.E., no Transfarring, Arial-esque font, character images on load screens, etc.)

• The animated cutscenes now run at 60FPS.
• The cutscenes can now be paused when pressing OPTIONS/+/Menu.
• Added the ability to customize the control scheme.
• The Nintendo Switch and Nintendo Switch 2 versions have local play for missions, similar to the original PSP version.
• The Japanese version has a free DLC pack to add language options for English, French, Italian, German, Spanish and Portuguese (Brazil). However, the international version does not offer a Japanese language DLC pack, unlike MGS 4 and the games in Master Collection Vol. 1.

v1.3.0#

Released on August 27, 2026.

• Added language support for Portuguese (Brazil) text.
• Added higher resolution video files for certain cutscenes.
• Added screen settings to adjust resolution (internal and upscaling) and movie cutscene quality, along with presets for original, adjusted, and high resolution.
