Vanguard Zombies’ sixth Objective calls upon players to disrupt a gruesome Dark Aether blood-magic ceremony. Grotesque structures known as Syphoncores will suck the essence out of the surrounding undead. Once they feed, the Syphoncores will spawn more zombies than they consumed, unleashing the horde upon the world. Prevent the zombies from filling all three, and the dark ceremony will be thwarted.
