In addition to the uniforms and volunteers that a player can get in-game in Metal Gear Solid: Peace Walker, another way to get them is by entering passcodes. By entering the passcodes below, a player can unlock more uniforms and volunteers that Big Boss can use. To enter the following codes, go to the Main Menu, and select Extras. In the Extras section, click Network, and then the player can now begin entering the passcodes.
More passcodes will be revealed as soon as we uncover them. The following passcodes have all tested and are correct. If you see a passcode that is not on the list, leave us a comment and we’ll add them in.
NOTE: A save file is required to unlock the uniforms and extra volunteers. The code only works ONCE.

Passcodes Revealed to Get New Uniforms and More in Metal Gear Solid: Peace Walker
As part of a bonus feature in Metal Gear Solid: Peace Walker, Big Boss can hunt monsters from the Monster Hunter series and earn unique items for completing them.
Without spoiling anything, the only time a player can unlock the Monster Hunter Missions in Peace Walker is when Chico joins the Mother Base. Before starting certain missions from the Main Ops, a player must look into the Briefing Files and listen to a specific conversation with Chico.
Below are the steps into unlocking the Monster Hunter missions:
1. Listen to the following conversations with Chico in the Briefing Files.
- After Main Ops Mission 5
(The Real Basilisco)
- After Main Ops Mission 8
(The Loch Ness Monster)
- After Main Ops Mission 10
- After Main Ops Mission 13
- After Main Ops Mission 15
2. After listening to the conversations from above, play the Extra Ops 29 or 35 as Snake. Go to the Coastal area and Trenya will appear on a boat near the bridge. Approach Trenya and trigger a cutscene and the mission will be completed. Once that is done, the Monster Hunter Extra Ops mission will now appear.
