Walkman

The Sony Walkman is a portable audio player featured in Metal Gear Solid: Peace Walker.

Militaires Sans Frontieres
A prototype to the then-in-development Sony Walkman in Japan, It originally belonged to Cecile Cosima Caminades to record bird sounds, but was confiscated by the Peace Sentinels after she stumbled upon one of the routine tests for the Mammal Pod. Pacifica Ocean later managed to steal it from the supply depot at Puerto del Alba. A few days later, Ramón Gálvez Mena used it to play back a tape that was allegedly from Pacifica Ocean's, aka, Paz Ortega Andrade's, friend for the commander of the private military group Militaires Sans Frontieres Naked Snake, which contained an all too familiar voice speaking with an unidentified woman. MSF's subcommander Kazuhira Miller initially believed that the Walkman was a Russian copy of the prototype, but later discovered and informed Snake otherwise. Snake kept the Walkman for the mission, and Mother Base's R&D team, under Miller's suggestion, studied the Walkman and were later able to reverse-engineer and improve it. In addition, the Sony Walkman was also used to play back recordings that contained briefings, discussions between two people in general, or even old data files. Paz also utilized the walkman to record her log on the events of her stay on Mother Base and her mission for Cipher. Presumably, the Patriots/Cipher and Strangelove also utilized a prototype Sony Walkman, as EVA sent a multi-part cassette tape regarding The Boss's mission between 1959 and 1962 to Big Boss and the MSF, and Strangelove made recordings on cassette tapes regarding her past with The Boss when anticipating Hot Coldman offing her after the project was finished, as well as asking the Mammal Pod to recount The Boss's experiences in Operation Snake Eater and the Virtuous Mission.

Description
"TPS-L2 The first edition of the "WALKMAN" stereo cassette player. Despite its lack of a record function, the WALKMAN defied naysayers in the company and in the public to touch off a revolution in personal sound systems and to create a whole new lifestyle. It features the metallic blue body color, akin to the color of blue jeans."

- Sony Walkman (TPS-L2) description from Metal Gear Solid: Peace Walker

Description
"WM-2 Unlike most consumer products, the WALKMAN II was created under a "design first, engineering afterwards" philosophy. Not only is it even smaller and lighter than the original model - barely the size of a cassette case - it is designed to maximize sound quality, with support for the clear, crisp stereo sound of metal tapes and a built-in anti-rolling mechanism. It's easy to see why the WALKMAN II was such a runaway hit."

Description
"WM-EX88 The EX88 takes the style and functionality of the WALKMAN in an entirely new direction. Its design still emphasizes ease of use above all else, but it also includes a number of handy new features, including track skipping, a hold shutter to keep it locked when not in use, and an "LCD song search remote" that displays play info on an LCD screen."

Description
"NWD-W202 A WALKMAN with integrated headphones. The display and other functions have been stripped down to the bare essentials to create a lighter, more compact system with simpler controls. It utilizes a spiral neckband to reduce slipping, making it ideal for working out. It also features the "ZAPPIN^ TM " function that scans songs and lets users enjoy the best parts in short continuous clips like a highlight reel."

Tracks
The Walkman can be accessed under the Control Menu (provided it was selected during mission preparations), and will play tracks on it instead of the standard BGM. Upon finishing a track, it will automatically begin the next track before starting all over. Once it is upgraded to Rank 3, track skipping allows the player to jump to the desired track. As R&D upgrades the Walkman, new tracks will be available to play.

Trivia
During the Zanzibar Land Disturbance, a cassette tape player was used by Gustava Heffner to record the Zanzibar Land National Anthem, which Snake later procured from her locker using her brooch's memory shaped alloy nature. However, it grew distorted from overuse.

Behind the Scenes
During Peace Walker's development, Sony released a promotional NWD-W202 Walkman that had green camouflage colors. Included with this walkman were pre-recorded music as well as a passcode that allowed a Walkman T-shirt to be released.

The Sony Walkman was the only real-life, non-DLC passcode-obtainable item that neither had its name/design/model viewer description changed nor had its briefing file topic removed during localization, most likely due to its major role in the plot. On a related note, it was also one of only three products, thanks to the promotional item's release, whose DLC passcode item was kept in releases outside Japan (the others being the Hori accessory line and the UNIQUO T-shirts).

If a soldier plays the Walkman, they'll gain the Earplug ability, which renders them incapable of being stunned by the various monsters' roars. This was a gameplay element carried over from the Monster Hunter series.



"WALKMAN Original t-shirt design. Identical in basic characteristics to Jungle Fatigues. WALKMAN fans, show your support!"

- WALKMAN description in Metal Gear Solid: Peace Walker

During battles with the AI weapons, when the player breaches the AI pod to steal its memory boards, the player could also retrieve a cassete tape after pressing a specific action button prompt. Depending on whether the AI weapon battle in question was the story mode version or the Type II/Custom versions in Extra Ops, the tapes retrieved are tapes relating to the Briefing file series "Strangelove's Memories" and "Paz's Diary," respectively, the latter of which also has Miller calling in questioning what a cassette tape is doing inside the AI pod.
