Season 2 is live for Call of Duty: Vanguard, which introduces the new objective-based Zombies map Terra Maledicta set in Egypt's Eastern Desert. This new starting «Temple» hub also serves as a continuation of Vanguard Zombies' ongoing narrative of the Vanguard operators helping Professor Krafft search for a way to stop Von List and Kortifex from using an army of the dead to win World War II for the Nazis. Here we walk you through completing this storyline Easter egg.

When spawning into a match of Terra Maledicta, you'll get audio dialogue from Vercanna the Last that instructs you to collect a page from the Tome of Rituals. From here, you must simply complete the portal objective that's on the east end of the starting hub to reach the shield. Once the area Merchant Road is unlocked, you'll see the new Wonder Weapon called the Decimator Shield, but the weapon is currently trapped.

Audio dialogue tells you the history of the shield and that you must break four crystals to free it from its trap. You're told you must gain Vercanna's trust before you can break the crystals. From the starting hub, find the objective portal facing North and complete it to unlock access to the Tents area of the map with the Demonic Frenzy (Speed Cola) perk fountain.

Complete the objective and then you can come back to the area to find the speaker stone. The stone is located against one of the tents located opposite from the perk fountain. Interact with it to get audio from Vercanna.

Once the dialogue is finished, Vercanna will open up a portal right in front of you. Enter the portal and you'll need to complete a Purge objective. This works just like the standard Purge objective. You simply stand on the glowing rune circles and kill zombies until
