Warzone Teasers Sent to Influencers Indicate April 21 Event

Real-world teasers about the next season of Call of Duty: Warzone have begun arriving at the doorsteps of Call of Duty influencers, teasing an in-game event for April 21.
The teaser, which Call of Duty talent Joe "MerK" DeLuca tweeted Tuesday, includes a hardhat with the Call of Duty: Black Ops Warzone logo on one side. On the other side, it sports a gas mask over the words "Verdansk Dam."

"Once the hostiles reach here, we levee a guess that Verdansk is all but gone to the damned. April 21st 12PM," reads the message included with the helmet.
The gas mask likely refers to the upcoming nuclear disaster that fans expect with cap off this season of Warzone. Verdansk Dam appearing on the helmet below the gas mask, taken alongside the use of "levee" in the message, indicates whatever catastrophe happens, it will likely happen there.
The reference to "the damned" also points toward zombies overtaking the map.
Although the note indicates the event will take place at noon on April 21, it doesn't specify a timezone. That could mean the event will take place in players' local times, but more likely it means noon PT, or 3 p.m. ET.
A Warzone glitch discovered last week appeared to preview the season-ending event, with nukes carpeting the map in an attempt to kill zombies that have overrun the island.
Activision has yet to confirm these details.
