The Haunting introduces a nighttime variant of Warzone’s Al Mazrah, teeming with demons and other spine-chilling bosses during the Operation Nightmare event. This special Halloween event requires you to hunt down various bosses to unlock exclusive rewards. This guide provides a detailed strategy for defeating each boss and attaining all possible rewards in Operation Nightmare.

All Bosses and Rewards

Completing each boss fight grants a unique calling card. Although that may not seem significant, overcoming all the bosses unlocks the Bloody Mess weapon blueprint for the BAS-P submachine gun, elevating the reward’s appeal.

The Butcher

Diablo IV’s Butcher makes an appearance in both Al Mazrah. Marked on your tactical map at the beginning of the game, this boss can spawn at random locations. The key to summoning him lies in activating pillars surrounding a ritual site. You must be prepared for zombie attacks with each pillar activation. A portal will appear after completing the full ritual. Stepping into this portal will face you off against the Butcher. He is a challenging adversary, accompanied by zombies, and requires substantial ammunition to defeat. It is crucial to stock up on items like munition boxes, armor plates, and self-revives. Defeating the Butcher rewards you with a Modern Warfare 2 (MW2) calling card and unlocks the Butcher’s meat hook for use in Diablo IV.

Swamp Creature

Exclusive to Al Mazrah, the Swamp Creature resides in the Mawizeh Marshlands. The primary task involves locating three egg pods in the swamp. However, opening these pods often summons the creature even before the Tiara, the necessary item to lure it, drops. Defeating this boss offers the Swamp Creature calling card as a reward.

The Pharaoh

The Pharaoh inhabits the Oasis area in Al Mazrah. To summon the Pharaoh, you have to kill possessed enemies that spawn around desert ruins, collecting skulls. Ten skulls must be placed in a sarcophagus to awaken the Pharaoh for a challenging battle. This fight requires teamwork and continuous movement to avoid being caught and executed by this fast-moving enemy. Overcoming this boss earns you the Pharaoh calling card.

UFO

Located in the Sawah Village, the UFO fight involves destroying anomalies: blue orbs that shoot lasers. It’s essential to wear full armor and utilize cover to withstand their attacks. After defeating the anomalies, the UFO appears, which must also be destroyed. Doing so unlocks the UFO calling card as a reward.

Ghost Train

Al Mazrah’s train morphs into a fearsome Ghost Train. The mission entails boarding the train to capture a heart item. With the train laden with explosives, such as proximity mines and claymores, caution is advised. Successfully reaching the front of the train and capturing the heart item rewards you with the Ghost Train calling card.

Evil Spirits

This challenge involves finding various spooky entities by looting containers at different locations. The successful completion of these steps will unlock the Evil Spirits calling card.

General Tips

Both battle royale and DMZ modes are viable options for completing these challenges. Nighttime Al Mazrah requires the use of night-vision goggles or thermal scopes for better visibility, especially against AI opponents in DMZ.
