- Revolver Ocelot describing XOF, based off the letters making up the name
XOF (also known as the Cipher Strike Force, or Sons of Ozone) is the confirmed main antagonistic Faction of the upcoming Call Of The Watch Dogs: Shadows of The Patriots, a Crossover between Ubisoft-Pixar and the Metal Gear Solid Franchise. This Faction is made up of the various surviving Villain Lords such as Skull Face after the Destruction of The Villain Armada, although its other Leaders are unknown. They mostly enlist veteran Armada Troops who went into hiding, but they also enlist Superhumans such as the Skulls Parasite Unit.
