Peace Walker Walkthrough
Use this as the story route through Peace Walker: clear Main Ops, prepare for the next major boss, and return to Extra Ops when Mother Base or equipment progression becomes the blocker.
How to use this guide
Main Ops are the story route. Extra Ops are the supporting loop for ranks, recruits, materials and equipment. When a Main Op feels underpowered, check the missions and weapons hubs before repeating the whole campaign.
Main Ops progression
- Follow the currently available Main Op and read its objective before choosing a loadout.
- After a boss or vehicle mission, review the result, staff and materials at Mother Base.
- Use Extra Ops to raise relevant staff, develop a better weapon or improve a rank before the next story checkpoint.
- Keep the mission hub open for unlock conditions; this page stays focused on what to do next and how to clear the route.
Boss-prep checkpoints
Vehicle and AI-weapon encounters reward preparation more than a single universal build. Bring an appropriate weapon class, enough support items and a plan for resupply; use the Bosses hub for the encounter-level overview and co-op notes.
How to reach the true ending / post-story progression
The post-story route is a progression task rather than a separate first-phase URL. Continue checking new Main Ops, complete relevant Extra Ops, develop Mother Base and follow the prerequisites listed in the Missions hub. Exact 2026-version unlock behavior is kept marked for verification until confirmed against the released build.
S-rank and 100% route
Treat S-rank replays as a second pass: first clear the story and unlock the tools you need, then return with optimized routes and equipment. The site does not split individual mission pages until a mission shows sustained search demand and has enough verified detail to support a complete guide.

FAQ
Common questions about this topic.
Is this a page for every individual Main Op?
No. It is the story-order and progression hub; individual mission pages need a later search-demand and content-depth gate.
Where should I go when I cannot clear the next story mission?
Check the Missions hub for prerequisites, then use Weapons or Extra Ops to improve the relevant staff, equipment and rank.
Where is the true-ending guide?
The true-ending bridge is included here and linked to Missions for prerequisites; exact 2026 unlock behavior remains clearly marked until verified.
