When Call of Duty: WW2 launches later this year, it will feature the a new version of the Nazi Zombies game mode seen in past iterations. Letting players team up to put enemies back in the dirt, the Zombies modes have been a popular component of the COD games for a long time now.

Fans are so excited, in fact, that they aren’t even prepared to wait for the Nazi Zombies trailer to be revealed in an official capacity. The full reveal for the mode, which is apparently called Army of the Dead, was set to take place on Thursday, July 20 at San Diego Comic-Con, but the trailer has leaked and has now been posted online.

Building on the incredibly creepy Nazi Zombies teasers and clues that were posted by developer Sledgehammer Games earlier this week, the trailer speaks of an army forged from “the flesh of our flesh [and] the blood of our blood.” The sinister voiceover, which may be that of a mad physician named Klaus, reveals that he is “building more than just soldiers” and that he has “created the devil himself.”

The gameplay looks appropriately tense, as grotesque enemies rush down corridors to try and take out the player characters. Players can get an (unwanted) look at the zombies’ innards, with the undead army looking as gross as ever thanks to Sledgehammer Games’ work. Towards the end of the trailer, the standard type of enemies seem to be joined by an even tougher looking opponent that’s brandishing a spiked melee weapon.

Teaser information for the returning Call of Duty: WW2 game mode speak of improvements to Barbarossa’s sword – meaning that the enemy’s attacks are likely to be devastating and should be avoided at all costs. The enemy also appears to be massive in size, suggesting that it could one of the mode’s mini-boss types.

The trailer only offers a quick glimpse of an actual firefight but based on this leaked footage, fans have plenty to get excited about. Not only does it seem to capture the frantic nature of Nazi Zombies, but it also delivers on Sledgehammer Games’ promise to make the mode “chilling.” The amount of zombie games released in recent years has taken the terror out of the characters, but Call of Duty: WW2 could make them terrifying all over again.

Call of Duty: WW2 releases November 6, 2017 for PC, PS4, and Xbox One.
