How to solve the Bunker 13 Easter Egg in Warzone

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. Moreover, 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 featured on the Urzikstan map (i.e., Battle Royale, Mutation Resurgence, or Plunder). Entering the bunker is pretty straightforward, but you need to have a Bunker Keycard (see image) to unlock the reward. The best way to get this item is by completing an Upload Intel contract.

Once you have a keycard, head straight to the Popov Power Plant situated in the north region. Plunder is the best mode for this challenge as there's no collapsing safe zone to restrict 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 above), you'll find a submerged tunnel entrance. Follow the directions shown below to reach Bunker 13 in no time.

1. Enter the indicated tunnel.
2. You'll reach a section with paths leading in multiple directions, but you need to enter the underwater tunnel I've marked in the second image (it may be a bit difficult to spot because of the grass cover).
3. From here, you just have to follow the tunnel to the other end while taking breaks to replenish your breath at the air pockets.
4. At the intersection (fourth image), enter the tunnel on your left and swim forward.
5. At the end of the tunnel, climb the ladder onto the platform and drop down the indicated hatch.
6. Enter the vent on your 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 items you can take to help you win the match. You haven't used the keycard yet, but it's required for the next and final step in solving the Easter Egg.

Look for the locked Treasury Room in the central section and open the door using the Bunker Keycard. It can't be unlocked without the keycard, hence getting it in the first place is an important part of the quest. Once you've unlocked the Treasury Room door, you'll get the Bunker 13 Easter Egg completion pop-up. With this, you would've unlocked the Bunker Buster weapon charm (second image), which you can equip in the Warzone & MW3 loadout customization menu.
