Check out the Operation Nightmare tab in Modern Warfare II and Warzone and check your Tac-Map for locations to investigate. Look for a unique entity somewhere in each location within night versions of Warzone. Take down each monster to earn a unique reward. All monsters can be hunted in Al Mazrah, while The Butcher can be found in both Al Mazrah and Vondel.

Killing at least five out of the six monsters in the Operation Nightmare unlocks the Bloody Mess Mastery Weapon Blueprint.
