Peace Walker

Lore & Background

The Peace Walker is one of four advanced AI-controlled vehicles encountered in Metal Gear Solid: Peace Walker, alongside PUPA, CHRYSALIS, and COCOON. Each of these vehicles has an AI pod that the player can infiltrate after sufficiently damaging the vehicle in a boss battle. Once inside, the player must remove AI boards from within to shut down the AI and fully defeat the boss. Depending on the player's strategy in defeating these bosses, vehicle parts and AI boards can be harvested and used to build Metal Gear ZEKE, a bipedal mech designed by Dr. Emmerich for MSF. ZEKE can be employed on Outer Ops missions as a support vehicle, and its level of development influences the difficulty of the final mission of the storyline. The game is set in Costa Rica in 1974 and follows returning protagonist Snake as he runs the mercenary unit Militaires Sans Frontières (Soldiers Without Borders).

In Their Own Story

Deep in the Costa Rican jungle of 1974, Snake faced the Peace Walker, an AI-controlled bipedal weapon designed by Dr. Emmerich. The machine stood as a testament to MSF's growing power, its AI pod glowing as it prepared to unleash devastating firepower. Snake knew that to defeat it, he would need to first damage its armored frame enough to infiltrate the AI pod. Once inside, he would have to remove the AI boards one by one, shutting down the machine's consciousness. The battle was not just for survival—it was for control of the future of MSF itself.

Reader's Guide

The Peace Walker is one of four AI-controlled vehicles in Metal Gear Solid: Peace Walker that serve as major boss encounters. To defeat it, players must first damage the vehicle sufficiently in a boss battle to expose the AI pod. Once the pod is accessible, the player must infiltrate it and remove AI boards from within to shut down the AI and fully defeat the boss. The strategy used to defeat these bosses determines which vehicle parts and AI boards can be harvested. These components are then used to build Metal Gear ZEKE, a bipedal mech designed by Dr. Emmerich for MSF. ZEKE can be employed on Outer Ops missions as a support vehicle, and its level of development influences the difficulty of the final mission of the storyline. The game features cooperative play for up to four players during battles against enemy vehicles and AI weapons.
