How to open all 11 Call of Duty: Warzone bunkers with red access cards

Players can open bunkers across Verdansk using red access cards, and they've returned in Modern Warfare Season 5.

Underground bunkers were discovered around the Call of Duty: Warzone map shortly after the free-to-play battle royale game was released back in March, but the ability to open them wasn't unlocked until May's version 1.21 update. At the time, everyone assumed that these bunkers were part of a bigger tease related to the next mainline Call of Duty game rumored for release later this year, supposedly Call of Duty: Black Ops Cold War. But following the launch of Modern Warfare Season 5 at the start of August, the red access cards needed to unlock the bunkers have returned with some noticeable upgrades, and there's also the mysterious introduction of blue access cards in the newly opened stadium.

To see what all the fuss is about, here's what you need to know to unlock these bunkers and try to uncover the deeper mysteries of Activision's battle royale.

Where are the bunker locations in Call of Duty: Warzone?

It's unlikely that you'll be able to make it to every bunker location during a single match, as they are all spread out across Verdansk. Thankfully, most of them are near major locations so you can find them with just a bit of effort scouring the environment. Depending on where you land, see which of the following 10 locations you should begin looking for. You'll need a Red Access Card gathered from chests to open the doors. Previously, they only dropped from legendary crates, but now they're in any colored crate, including common crates.

Season 5 also introduced a new red card icon with the shape of a key on it that appears next to the name and health of any active player. YouTuber MrDalekJD claims that the new red key cards will open bunkers 0, 4, 5, 6, and 9. Other bunkers are seemingly inaccessible, but things appear to be constantly in flux.

Inside these bunkers, players can find all sorts of top-tier loot, but curiously, but there's also a keypad inside these bunkers, which is new in Season 5. Thus far, no code seems to work, but it seems like that will change over time.

Here are all 11 bunker locations on the 'Call of Duty: Warzone' map.Activision

What rewards do you get for visiting a Call of Duty: Warzone bunker?

These 10 bunkers are worth visiting as they contain excellent loot thanks to Legendary Supply Boxes, weapon blueprints, and money scattered around each of them. Still, they do have locked doors, suggesting that there is more to these bunkers than currently meets the eye. As Activision begins to tease Call of Duty: Black Ops Cold War more and more, expect these bunkers to only become more interesting and useful.

Where is the secret bunker in Call of Duty: Warzone?

While 10 regular bunkers, there is an eleventh secret bunker in Call of Duty: Warzone. It can be found northwest of the military base in Bloc 23 near the edge of the map. Unfortunately, you can't access it immediately. In order to access the bunker, you'll have to gather intel from a series of message phones scattered across the map and decipher a code. You'll get a three-digit number encoded in Russian. Using that number, you must then visit different Morse code phones in the correct order. (GamesRadar has a handy guide for that.)

While the three-digit code given is randomized, the specific phone locations they reference are not. After picking up the phones for all three, the eleventh bunker will be unlocked. (It's the northern-most red dot on our above map.)

Inside the bunker, you'll receive a blueprint for a legendary MP7, so it's definitely worth going out of your way to find. That said, it may be best to do this in Plunder as the shrinking arena of the battle royale mode will make it hard to get to this final bunker most of the time.

Call of Duty: Warzone is available now for PC, PS4, and Xbox One.
