The latest update on Call of Duty: Warzone brings several changes and fixes, along with Bunkers, which are slightly different from the previous updates.
Bunkers in Warzone are hidden underground locations that contain high-tier loot, cash, and special items.
Each Bunker in Warzone can only be unlocked with a specific code or Access card, including Blue and Red.
Open Bunkers In Warzone With Keycards
Bunkers are back in Warzone, with each bunker requiring codes and key cards to be unlocked.
The Bunkers you open will mostly contain valuable loot, and a few of them will also contain valuable weapons.
Among all the available 12 bunkers, you will find that 3 or 4 bunkers require a Blue Key Card to be unlocked, while 4 bunkers can be unlocked using Red Key Cards.
In the meantime, the remaining Bunkers are likely to be unlocked with the codes, which you can obtain by decoding the Morse codes via ringing the phone.
Use Blue Keycard To Unlock Bunkers In Warzone
The Blue Keycard can be obtained through the random chest in different map regions, while I found it around the Prison area.
Additionally, the Blue Key card can also be found in the chest inside Bunker 11. So if you have unlocked Bunker 11, you can access the blue keycard.
Once you have the Blue Key Card, you can head towards the Bunker near the Stadium area and use the card to unlock the Stadium Easter Egg.
Among the 3 or 4 Bunkers opened by Blue Key Card, Bunker 2 will contain Nuke Schematics and a free UAV.
The Nuke Schematics you obtain from Bunker 2 can be used in Bunker 10 to build Nuclear Weapons and Armor.
Once you have unlocked all three Blue Bunkers, you can head towards the other Bunkers and use the Red Key Card to unlock them and collect free materials.
