Killstreaks in Warzone works a bit differently than in other Call of Duty games. While the way they are used the same way, obtaining them is based on how much cash you have.
In COD: Warzone, you need to buy the Killstreaks from Buy Stations. There are only four Killstreaks in Warzone and you can only buy only one Killstreak at a time for balance purposes.
Note that if you have Hardline perk in your loadout, then you will get 25% off on all Killstreaks, Armor Plates and Field Upgrades.
Let's take a closer look at the Killstreaks available in Warzone.
Originally you could buy a Shield Turret Killstreak from the Buy Station for $2,000 ($1,500 with the Hardline perk). It has since been replaced with the Armor Box at the Buy Station with the release of the new Update 1.21. You can still find the Shield Turret Killstreak as ground or supply loot. You can deploy this turret anywhere on the ground and then use it to eliminate enemy players.
The turret has a very high damage rate and can eliminate enemy players quickly. It is partially shielded so you also get some protection while using it, but only from the front.
Cluster Strike can be bought for $3,000 ($2,300 with the Hardline perk) from the Buy Station.
This Killstreak gives you the ability to call a number of cluster mortars on a designated location. You get a laser targeter that you can use to paint the target of the strike.
We recommend tracking your target through a sniper scope!
The Precision Airstrike Killstreak is a slightly more powerful version of the Cluster Strike. It can be bought for $3,500 ($2,600 with the Hardline perk).
You can use this Killstreak to call in twin jets for a precision airstrike along the best available path. You get binoculars which are used to target a specific location to call in the strike on.
The UAV Killstreak can be brought for $4,000 ($3,000 with the Hardline perk) and will call in a UAV recon ship that reveals enemy locations on the minimap for a brief period of time. You will notice a pulse being sent out from your location on the minimap, which will illuminate colour coded blips.
If you call in three UAVs at a time with your squadmates, then you will activate an advanced UAV which will reveal the location of all the enemies on the map for the period of time the UAV is available. During this advanced UAV period, enemies stay on the minimap and you can also see the direction they are looking.
