Trivia / Metal Gear Solid: Peace Walker

• Acclaimed Flop: Zigzagged. The original Western PlayStation Portable versions of the game didn't sell well at all, but thanks to its inclusion in the Metal Gear Solid: HD Collection it was given a much wider audience.
• Alan Smithee: Just like in Metal Gear Solid 3: Snake Eater, EVA is voiced by an actress credited as "Suzetta Miñet", which had been confirmed to be a pseudonym. The true identity of the actress remains unknown.
• Executive Meddling:
  • The Japanese version of the game had to edit its torture scene to utilizing "Laughing Rods" instead of shock rods because of the censors demanding they do so to maintain their "C" rating (ages 15 and up).^note Had to do with the CERO policy that depictions of violence against a restrained person will bump the rating to around D and companies prefer to have the A rating if possible.
  • In the Western versions, some items had to be changed because they were real world products.^note Even though one of the products, Pepsi NEX, was not actually available outside Japan.
• Enforced Method Acting: According to David Hayter in Kojima Productions Report Session 117, he actually vomited in the sound booth in order to produce some of Snake's choking sound effects for the game.
• Fake Nationality: Due to the "independent from any nation" spirit of the Militaires Sans Frontières, the fake accents vary:
  • British-born Robin Atkin Downes uses his Fake American accent to voice the Japanese-American Kazuhira Miller.
  • Canadian Tara Strong voiced the Costa Rican Paz Ortega Andrade. She also uses a pseudo-Russian accent for Pacifica Ocean.
  • American Vanessa Marshall voiced the British Dr. Strangelove.
  • American Catherine Taber voiced the Parisian ornithologist Cécile Cosima Caminades. As a result, when her character had to actually speak French, she would simply sound like an American woman attempting French.
  • American Grey DeLisle voiced the Nicaraguan Amanda Valenciano Libre.
• In Memoriam: Peace Walker was dedicated to Project Itoh, author of the Metal Gear Solid 4: Guns of the Patriots novelization, who died before Peace Walker was released due to a long struggle with cancer. He was working on a tie-in novelization to Peace Walker prior to his death, which ended up being written by another author (Kenji Yano) and published four years after the game's release.
• Teasing Creator: The only possible explanation for the two "date" missions. Hideo Kojima is laughing at all of us. Fortunately, we can laugh along with him.
• What Could Have Been:
  • Kojima originally had no intention to direct Peace Walker. He intended to write only a rough outline of the game's plot and leave the rest to his younger staff, much like he did with the previous PSP games in the series, Metal Gear Ac!d, Metal Gear Ac!d 2 and Metal Gear Solid: Portable Ops, but he changed his mind when his younger staff did not understand the story's theme of nuclear deterrence.
  • A dinosaur version of Metal Gear RAY, named Gear RAY, was supposed to appear alongside Gear REX during the Hunting Quests.
  • The train that Snake was supposed to stop the shipment of nukes by the Peace Sentinel was originally intended to be a playable level. If the storyboards are of any indication, that train would have ended up being shot off the tracks and plummeting.
  • Peace Walker was originally supposed to heavily resemble Metal Gear REX, down to the rail gun and even the design of its hangar was supposed to mirror REX's hangar on Shadow Moses.
  • Paz and Zadornov would have been discovered earlier to not be trustworthy (especially Paz), where Paz and Zadornov are overseeing its construction, and Big Boss discovers their affiliation to the Peace Sentinel by eavesdropping from a window in a manner very similar to how Solid Snake eavesdropped on Liquid Snake and Revolver Ocelot's conversation in Metal Gear Solid before Coldman finds and surrounds him. Coldman was intended to be killed by Zadornov alone with a gun to the head, and at some point later, Paz would actually do the very same to Zadornov before hijacking ZEKE. If some of the storyboard sketches are anything to go by, Big Boss was apparently going to actually lead his troops on a sneaking mission rather than going in alone. An entire character model, the AI lab workers, who were implied to be of German origin, was also cut.
  • DLC was originally planned, but never came to be.
  • Originally, Project Itoh was working on the novelization for the game. Unfortunately, he passed away on March 20, 2009, leading to Kenji Yano, under pen name Hitori Nojima, taking on the job instead.
• Write Who You Know: Cécile is based on the former communications manager for Konami Paris, Cécile Caminades, in name and appearance.
