Metal Gear Solid V: Ground Zeroes - All XOF Unit Patches Location Guide

There are a total of 9 XOF Unit Patch Locations in Metal Gear Solid V: Ground Zeroes. Finding all XOF Unit Patches will earn you the “Insignia” Trophy or Achievement.
They will also unlock the “Déjà-Vu” Extra Op.

All of the XOF Patches are scattered across the “Ground Zeroes” mission. That’s the only main mission in the game and it’s available from the beginning on.
After picking up a collectible you need to reach the next checkpoint to save the progress. If you die before saving the game, you will have to collect it again.

The last XOF Unit Patch requires you to roll around on the ground. Hold X (PS3) / A (X360), then aim your weapon and hold down the left stick to start rolling. This will initiate a cutscene and the last patch will fall from the sky. Be sure you are somewhere outside when doing this. The other 8 unit patches can be picked up like normal collectibles, but they are hard to see. Pause the video and put a marker on your map to locate them easily.

The trophy / achievement will unlock after beating the story (which consists of only this one story mission). Shortly after the credits are over, you will see a screen with your rewards. That’s when it should unlock.
