All of the Call of Duty: Warzone bunker codes have been detailed in a simple to read map by a reddit user.
Reddit user "Content Conch" recently put together a map that makes finding and accessing all the bunkers in Warzone much easier. He stated that he found previous maps difficult to read, which inspired him to make his own.
Warzone Bunker Codes
The map clearly depicts where players can find the red access cards needed to unlock the bunkers. Once found, Content Conch's map shows you where the actual bunkers are found as well. Paired with the geolocation on a map of Verdansk are images of the entrance to each bunker, as well as images of where exactly the red access cards are.
Above each image of the bunker entrances is the code needed to unlock the door. Everything you need for each bunker is located in one precise spot that is clean and well put together. Color coding makes it easy to distinguish bunkers from red access cards and the codes are clearly paired with their respected bunker.
Content Conch shared the map on reddit and on a website that called Warzone Strategy that can be accessed here.
