You can complete the challenges in this event for exclusive rewards such as calling cards, charms, emblems, stickers, and a legendary Adler skin called ‘Tortured & Rescue.’ There is a total of six challenges - three for Warzone and three for Black Ops Cold War. Each challenge gives you an exclusive reward upon successful completion. But, for the legendary Adler skin, you only need to complete either three Warzone challenges or three Black Ops Cold War challenges.
In Warzone, the Adler Intel contracts have a unique icon on the map. There are limited Adler contracts each match, so you need to be quick to get to them, or else someone else will grab the contract. You will need to start another game or move to another Adler contract (if available, which is almost impossible as everyone is doing these contracts).

Legendary Adler Skin
If you complete either only the Warzone challenges or only the Black Ops Cold War challenges, you will be rewarded with a legendary Adler skin called ‘Tortured & Rescued.’ You must complete all three Warzone challenges or all three Black Ops Cold War challenges, or else it won’t work. Even if you complete two Warzone challenges and one Black Ops Cold War challenge, it will not work. The combination of both games and their challenges is not applicable.
