Insider Gaming has been given footage of a walkthrough of Building 21 in Warzone 2 DMZ. The footage shows a complete walkthrough of Building 21, which is currently not available in the game.
According to CharlieINTEL, the developers have said that the map has not gone live in today’s update and Infinity Ward has said “it’s up to players to figure out when it’s live and how to get into it.”
It’s currently not known how you’ll access Building 21 in Warzone 2 DMZ, but the developers have confirmed that “new keys have appeared in Al Mazrah” with the Season 1 Reloaded update, suggesting that it will be accessed via a key.
It’s likely that a new challenge or set of new challenges will also need to be completed in order to access Building 21. Officially, the area is a “clandestine biological laboratory” and its “location is classified”.
It’s also been said that “safes and special areas that require keycard access”, so players will need to make sure they have the right amount of loot before tackling the area.
Sources have said that Building 21 is accessible via multiplayer, so it’s possible that the map could be a multiplayer map in the future.
