Prepare for frightening thrills, the shambling undead, squad hunts to take down grotesque monsters, and those infamous jump-scares as The Haunting returns to Call of Duty! The Hellmouth has opened, spilling unearthly creatures from the underworld, and a creeping terror is slowly swallowing all souls as it infects the entirety of Al Mazrah, reaching the bloodred canals of Vondel, and beyond! It appears a clandestine group known as the Dark Ritual Operators have located and opened a terrifying Hellmouth. After the gate’s seals were ripped apart, a cacophony of otherworldly gurgling resounded, before a veritable panoply of the grotesque poured forth from their opened prison… All Operators should ready themselves for “Operation Nightmare” and prepare to battle and repel these aberrant threats! Fortunately, in the ensuing chaos, the Dark Ritual Operators left the gate open in time for backup to arrive in the form of Spawn, the hellacious antihero who is now tasked with sending these monsters and their ilk back to the underworld. The Haunting event officially begins at mid-season, bringing Halloween-themed maps, modes, events and more across both games. Prepare for spine-chilling scares and ferocious battles ahead at launch with the release of four new Multiplayer maps, a Battle Pass stocked with devilishly entertaining new Operators and Weapon Blueprints, and more.
