Will feature a heroes vs. villains mode.
Call of Duty Last Stand

On August 24, the final seasons for both Call of Duty: Vanguard and Call of Duty: Warzone will begin. On this date, there will be a new Heroes vs. Villains Community Event, Operation: Last Call, two new multiplayer maps, and a new Zombies map set in Egypt called "The Archon."

In Last Stand, four of the most notable villains in Call of Duty history will return. You can play as or play against Raul Menendez, Khaled Al-Asad, Gabriel T. Rorke, and He "Seraph" Zhen-Zhen. In Warzone, you can either wreak havoc or defend the island from sabotage all while Caldera's Peak rumbles to life. Multiplayer adds two new multiplayer maps, Beheaded and Fortress. In Zombies, you will continue the Dark Aether saga and face off against Kortifex the Deathless.

The new mode, Operation: Last Call, is a bit like Search and Destroy. This is a limited-time mode where you can choose to defend Caldera by defusing bombs around the island. You can also just sabotage it by detonating explosives at designated bomb sites.

This update also adds in a bunch of other content. There is the new Caldera Peak point of interest, a rage serum, UAV killstreak supply box, personal supply box, something called the Doomsday Station, a handful of new weapons, and new cosmetic bundles.

Doomsday Station
Discover this seismic device found within Caldera’s primary Battle Royale game mode. Trigger the device and enemy helicopters arrive to surround the station, deploying enemy soldiers to attack your position. Remain close to the Doomsday Station and defend yourself for a chance at earning powerful items and a unique Watch cosmetic for your Operator.

Only one Doomsday Station will appear per match, with multiple possible spawn locations. Pay the required $10,000 to activate it and prepare for a thunderous fight.

Supply Box UAV
Activate the new Supply Box UAV Killstreak for assistance in tracking down more items. It will mark nearby unopened Supply Boxes on the player’s Tac Map for around 15 seconds. Find the Supply Box UAV in Supply Boxes or purchase one at a Buy Station.

Personal Supply Box
Track down this extremely rare crate with the assistance of the Supply Box UAV to acquire your favorite Loadout weapons in Warzone. Each squad member gets a huge XP boost as well.

Rage Serum
While engaged in a multitude of nefarious activities at the Doomsday Station, forces aligned with Raul Menendez appear to have discovered a new mineral at the core of Caldera. This mineral, when combined with additional chemicals and distilled, increases the volatility of those who inject it. Known as the Rage Serum, Recon Operators have reported small crates of Serum being shipped around the island.

This Field Upgrade allows you to become violently unstable, resulting in a viciously effective boost to your close-quarters fighting. Test subjects were shown to have superior melee damage, increased lunge distance, and enhanced stun power while fighting with melee weapons or fists. However, defensive forces have confirmed that while affected by Rage Serum, an Operator becomes louder, and seems to recoil with more confusion while stunned or flashed.
This fifth and final season of content for Vanguard goes live on August 23 at 9AM (PT). The Warzone update goes live at 9AM (PT) on August 24.
