Call of Duty Warzone's bunkers are spread across the map. Most have multiple entrances, but all are inaccessible without the combination for a keypad beside each door. Players don't get a chance to enter a combination when interacting with these keypads, indicating they'll need to find something in-game to unlock the doors. Here's what we know about these bunkers so far.
Call of Duty Warzone Bunkers: Where to Find Them, How to Enter
There are 11 bunker doors in Warzone. Three can be found around Jarvoinsk Spomenik, two northwest of Junkyard, one between Junkyard and Kart Racing Track, one southeast of Styor Spomenik, one northeast of Zordaya Prison Complex, two on the west side of Karst Bridge, and one as far north as a player can travel on the Bloc 18 side of the river.
So far players have only managed to enter the bunkers by glitching inside with drones. Doing so reveals nothing — Infinity Ward has yet to add content behind the doors. That indicates players likely won't be able to enter legitimately until the release of some future update.
