Building 21

Building 21 is a map featured in Call of Duty: Warzone 2.0 and exclusive to the DMZ mode. The map was first released on December 19th, 2022 as part of Season One Reloaded update for Call of Duty: Modern Warfare II and was available for 24 hours. The map then became available on weekends for players who acquire a Building 21 Access Card. As of Season Six, the map has no time restrictions and is always available.
==Overview==
Set in the Defense Research Center, a match of Building 21 lasts 13 minutes with three exfil elevators opening at different times. Originally, only Shadow Company Armored Agents were featured in the map, but following the Season Five update, Konni Group Armored Agents were added into the map. The number of Konni and Shadow Company Agents both increase as the Protection Levels rise, as do their armor, from Alpha to Echo, when players are detected by security cameras or make noise. The security cameras can be destroyed. Velikan can be found on the map, using a RGL-80, when the Protection Level rises to Delta at around four minutes.
At the end of the thirteen minutes, players will have four minutes to perform a Final Exfil. If all elevators were used during the initial 13 minutes, they will all re-open during this period.
