With the Season 4 Reloaded update, the Call of Duty: Warzone playlist received a new game mode called Mutation Resurgence along with some changes to the Popov Power POI in Urzikstan. In addition, the new Bunker 13 Easter Egg was also added; here’s how to solve it to unlock the Bunker Buster weapon charm for free.
How to unlock the Bunker Buster charm in Warzone
Bunker 13 can be visited in any game mode presented on the Urzikstan map (ie, Battle Royale, Mutation Resurgence, or Plunder). Entering the bunker is quite simple, but you must have Bunker Key Card (see image) to unlock the reward. The best way to get this item is by completing Upload Intel contract.
Once you have a key card, go straight to the Popov Power Plant located in the northern region. Looting is the best mode for this challenge, as there is no collapsible safe zone to limit your movement across the map; however, you may have to compete with other players trying to solve the same Easter Egg. At the marked point (see image), you will find a submerged tunnel entrance. Follow the instructions shown below to reach Bunker 13 in no time.
- Enter the indicated tunnel.
- You’ll reach a section with paths leading in several directions, but you have to enter the underwater tunnel I marked in the second picture (it might be a little hard to spot because of the grass cover).
- From here, you just have to follow the tunnel to the other end while taking breaks replenish your breath at the air pockets.
- At the intersection (fourth image), enter the tunnel on the left and swim forward.
- At the end of the tunnel, climb the ladder onto the platform and drop down the indicated hatch.
- Enter the vent on the right, go through the doors, and you’ll reach the central section of Bunker 13.
Bunker 13 has several supply boxes and other ground loot that you can pick up to help you win the match. You haven’t used the keycard yet, but it is required for the next and final step in solving the Easter Egg.
Look for the locked one Treasury in the central section and open the door with the Bunker Keycard. It can’t be unlocked without the key card, so getting it in the first place is an important part of the quest. Once you’ve unlocked the Vault Room door, you’ll get the Bunker 13 Easter Egg completion. With this, you would unlock the Bunker Buster weapon charm (second image), which you can equip in the Warzone & MW3 customization menu.
