Project Peace Walker

Developed by: Huey Emmerich and Strangelove, Peace Sentinel (Peace Walker Incident) and Elisa Karkivo and White Blizzard (in 2067)

History: In the early 1970s as part of the Peace Walker Project, the AI units had various tech abilities such as high speed, mobility or destructive power.

Under the directive CIA Station Chief Hot Coldman, the Peace Sentinel successfully developed four types of AI weapons. Codenamed Pupa, Chrysalis, Cocoon, and the Peace Walker, they reflected hovercraft, flying, treaded, and walking-type vehicles, respectively. Each was equipped with at least one AI pod containing the artificial intelligence that operated the vehicle's frame. Each also had a speech synthesis system, for relaying verbal communication on the battlefield to surrounding forces. Although their development was largely unknown to the public, rumors nonetheless circulated.

The AI weapons' main development was headed by Huey Emmerich, while Strangelove created Peace Walker's advanced decision-making AI system, known as the Mammal Pod. Peace Walker was the final culmination of AI research gathered during the development of Pupa, Chrysalis and Cocoon. As such, the names given to the three prototypes all referred to the transformation stage of a butterfly's life cycle, while Peace Walker itself was often referred to as "Butterfly," and its Mammal Pod, the "Imago." In addition, other than the AI pod(s), the heads of the AI weapons themselves also functioned as a core to their main weapons, which would result in usage on other unmanned weapons should they be salvaged.

The AIs belonging to the AI weapons for the Peace Walker project's speech synthesis system repeated pre-set messages that would play depending on the situation. Peace Walker was the only one of the AI weapons from this project, as well as the AI weapons overall (counting ZEKE) that was capable of self-generated speech.

In 1974, Big Boss and MSF (Militaries Sans Frontieres) encountered each of these machines while attempting to investigate the Peace Sentinel's presence in Costa Rica, who were also transporting nuclear weapons into the country. Upon Huey's defection to the MSF, the MSF learned from Huey the methods of defeating the AI weapons, although they were forced to choose between the spare parts and the AI memory chips. After dealing enough damage to each weapon, and gaining access to the interior of their respective AI pods, Big Boss and MSF ripped out the memory boards of the AI itself, in order to disable it. After being tampered with by the MSF, the AI pods of the Pupa, Chrysalis, and Cocoon, weapons detached themselves from the main frames, and launched themselves on an escape vector, using their built-in rocket boosters.

When infiltrating the Peace Sentinels' mine base, the MSF discovered various inactive Pupa frames, indicating that the other AI weapons were intended for mass production, in addition to Peace Walker.

After the events of the mission, the MSF used the parts and memory boards they had salvaged from the AI weapons to create Metal Gear ZEKE

In 2063 during the girls frontline, the White Blizzard formation led by Ryan Annaklych (half American and Half Poland) their home based is at Germany recovered the CIA weapon called the Peace Walker Project, they decided to recreate the Peace Walker Project and AI Mammal Pod, first they recruit Elisa Krakivo to developed the AI mammal Pod since the Technology and Relic Technology created, Ryan Annaklych was indeed the descendant's Agent of the American Philosophers

In 2067, the White Blizzard set up the base in Iceland near the America's turf, while URNC and NSU conduct secret base for  implemented many land reclamation policies such as the Purification Project and the European Collapse Radiation Contamination Zone Restoration and Revitalization Joint Development Agreement led by Daniel West leader of the 4721nd Platoon codename "Svetovit" were also there in Iceland, unware for URNC, Daniel West secretly developed the Metal Gear on its own without word for URNC.
