Serving as one of the main collectibles in Metal Gear Solid 5: Ground Zeroes, finding every XOF patch hidden throughout Camp Omega will net you the Insignia Trophy/ Achievement. More importantly though, tracking them all down will also unlock a bonus format-specific Extra Ops mission--Déjà-Vu on PS3 & PS4, Jamais Vu on Xbox 360 & Xbox One--which should make this task appeal to more than just the completionists.
The XOF patches are pretty well hidden, so head to page 2 where we'll show you exactly how to find them all and gain access to that exclusive mission.
