Warzone challenges are currently bugged and cannot be registered or tracked upon completion. We are expecting a fix very soon, as the game developers are currently investigating this issue. If you're looking just to unlock the Adler skin, you may complete the Black Ops Cold War challenges, and you will be rewarded with the skin. If you're looking for the rewards associated with the Warzone challenges (emblem, sticker, etc.), then, unfortunately, we will have to wait for a fix.
With the release of Season 3 of Cold War Warzone, you can now jump into Verdansk '84, and complete specific contracts to get clues about the whereabouts of Adler. In this regard, there is a brand new limited-time, cross-game event introduced in Black Ops Cold War and Warzone.
TOP GAMEPLAY HIGHLIGHTS
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).
Warzone Challenges & Rewards
The following are the challenges and their respective rewards that can be completed in Warzone. Note that you can complete these challenges in both Battle Royale and Plunder mode.
Black Ops Cold War Challenges & Rewards
The following are the challenges and their respective rewards that can be completed in Black Ops Cold War Multiplayer.
- In Cold War, kill 25 enemies who have been revealed by your Spy Plane, H.A.R.P., or Field Mic.
- Reward: Pager (Rare Charm)
- In Cold War, kill 25 enemies on a killstreak while using the Assassin Perk.
- Reward: Vengeful Commando (Epic Calling Card)
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.
