Warzone’s highly-anticipated Operation Monarch event brings Titans King Kong and Godzilla to Caldera, but there are also challenges to complete and rewards to earn. Here’s how to complete both the event challenges and the secret challenges, as well as all the rewards you can earn.

Call of Duty: Warzone has featured a handful of crossover events, bringing Rambo and John McClane for the 80s Action Hero event, and Ghostface for The Haunting, and Operation Monarch is the latest to arrive.

Godzilla and King Kong tower over Caldera in the Operation Monarch LTM and players can earn a ton of free rewards for battling them including Calling Cards, Emblems, and the exclusive Ancient Rivalry Blueprint.

Here’s every Operation Monarch event challenge in Warzone Season 3, including the secret challenges, as well as their rewards.

Raven Software also teased that there will also be challenges that are separate from the eight needed to unlock the Ancient Rivalry Blueprint, where players can unlock additional Charms, Calling Cards, and Player Titles.

It’s worth bearing in mind that the reward might not correspond to the exact challenge, as in the chaos of Operation Monarch, players had trouble figuring out exactly what they did to trigger the reward.

The first secret Operation Monarch challenge has been set by Mountain Dew, where you just need to eliminate three enemies with a Flaming Throwing Knife to unlock a unique Calling Card. If you haven’t bought it from the store, we recommend picking up the ground loot version and using it on downed enemies.
