Modern Warfare 2 and Warzone 2 Season 1 Reloaded have officially kicked off, bringing a brand new assault rifle called Chimera to the weapon’s pool. Although the weapon can be unlocked for free, it doesn’t mean that you can obtain it right away. One of the ways to snag Chimera in Warzone 2 is by extracting it from Building 21 in DMZ gameplay mode.

However, if you’re new to the game, you will have a hard time finding Building 21 in the game. Even if you somehow manage to find the building, finding its key is still a daunting task. Therefore, we’ve got you covered with this essential Warzone 2 guide that provides you with a detailed breakdown of the Building 21 location and its key in DMZ mode.

As of writing, the Building 21 area isn’t live in the game, so its location is unknown at the moment. In fact, Infinity Ward has confirmed that the region will not go live with the Season 1 reloaded update. Instead, the developers will roll out Building 21 with one of the upcoming Warzone 2 updates.

On top of that, the update will not be announced to the players. Therefore, they need to figure out when it’s live and how to access it.

As we’ve already mentioned earlier, Warzone 2 players require a special key to access Building 21 in DMZ. In the official blog post, Activision confirmed that new keys have appeared in Al Mazrah, but their location is hidden at the moment.

However, it’s being assumed that Building 21 key can be obtained by killing AI enemies and looting their crates. Apart from this, opening the Commander Helo and Airplane supply drops can potentially reward you with a key.

So that’s it, everything you need to know about finding Building 21 DMZ Location and its key in Warzone 2.
