A lot of the perks work differently in Call of Duty: Warzone compared to other titles in the series, particularly Modern Warfare.

You can only access the following perks if you get your custom loadout from the Loadout Crate drop. You can choose up to three perks as usual. Also, choosing the specialist feature is useless for Warzone as it has no effect in it (it's is only effective in Modern Warfare multiplayer).

Let's take a look at some of the perks you should have when playing COD: Warzone.

Perk 1 - Cold Blooded

The Cold Blooded perk is one of the most important perks in this game. It is essential in Modern Warfare's multiplayer, but plays an even more important role in battle royale.

While you have this perk, you won't be visible on enemy thermal optics, and spotting players before they spot you gives you a huge advantage over them. If you rush them first, then you get the element of surprize, which is invaluable.

Another advantage of the Cold Blooded perk is that it makes you undetectable by enemy AI targeting systems. Even if the enemy player has the High Alert perk then their vision will not pulse if you see them outside of their vision. Perk 2 - Ghost The Ghost perk is an absolute no brainer. When you have the Ghost perk, you are undetectable by enemy UAVs, Radar Drones and Heartbeat Sensors.

Most players go for UAV in Warzone and they quickly use this killstreak the instant they fear that someone is nearby. We recommend you always keep the Ghost perk in all of your Battle Royale custom loadouts if you wish to remain unseen during the match.
