What is Building 21 in the DMZ?

Building 21 is a multi-floored facility that houses a biolaboratory. Inside, you’ll find valuable information, stacks of cash, and various valuable items.
However, be prepared to face formidable enemies who will stop at nothing to prevent you from completing your faction missions and escaping with the crucial data.
On all three floors of Building 21, challengers are present. When you arrive at Building 21, the objective is to reach the server room.
However, you’ll need to wait until the security system is deactivated to proceed.
Throughout this period, you’ll encounter AI challenges that will put your squad to the test.
After dealing with all the adversaries, head up to the armory on the top floor.
The place is situated behind a vibrant orange door and is filled with fantastic treasures.
Take as much as you can and then return downstairs, making your escape using the elevator.
It’s a real challenge, with narrow office corridors and tricky spiral staircases designed to keep you on your toes.
And let’s not forget about the other players who are fully equipped and ready to hunt you down for your valuable gear.
However, you can’t just choose Building 21 from the map selection screen and drop in.
Access to the entry requires a Building 21 Access Card, which is essential for gamers.
Completing Building 21 will give you the following rewards:
- Camo Cloud Vehicle Skin
- Company Sniper Emblem
- Going Bark Weapon Charm
- Roar Weapon Sticker
- Silver Tox Chimera Blueprint
- Weapon Rover Calling Card
As you can see, Building 21 presents an immense amount of danger. Getting access to it is even a little bit difficult.
However, the prizes and loot are absolutely unquestionably worth the effort.
When Can You Access Building 21?

Access to Building 21 is restricted to a specific time frame, so entry is not permitted without proper authorization.
It may seem a bit perplexing initially, but Infinity Ward does have a well-established schedule that you can adhere to.
Building 21 is only open on the weekends, just so you know.
To gain entry into Building 21, it is necessary to acquire a Building 21 Access Key through a DMZ run.
The cards can be found in orange high-quality loot containers in Al Mazrah, but they are extremely difficult to come across in the wild.
I suggest purchasing the Building 21 Access Card directly from a Buy Station.
Nevertheless, the price tag for this item is quite substantial—$40,000, to be precise—and you will have to extract the card in order to utilize it.
Infinity Ward will provide players with advance notice before Building 21 closes.
This guarantees that players do not encounter any interruptions that would prevent them from successfully finishing a mission.
What is the reason behind your desire to enter Building 21?
Building 21 is a multi-level facility with a multitude of AI adversaries and a plethora of enticing treasures.
However, it is important to note that there will be numerous other teams present, as several faction missions necessitate entering the area.
There will be numerous encounters that require preparation.
How to enter and beat Building 21 in DMZ

Alright, so it’s the weekend. What’s next?
After winning the card, you will have access to Building 21 exclusively on weekends.
The event is only available from late Friday night to late Sunday night CT, so make sure to mark your calendars!
After the sun rises on Monday, you’ll unfortunately be unable to access the area until the following week.
One of the initial tasks is to locate a key that grants access to Building 21.
Sure, here’s a key. It’s worth noting that in DMZ mode, you’ll soon discover that everything requires a key!
Inside Building 21, you’ll find a wide range of objectives to tackle.
These include faction missions, the challenge of defeating the miniboss Velikan, and the opportunity to acquire his powerful RGL-80 grenade launcher.
Similar to other keys, the one required to access Building 21 is unfortunately assigned at random.
However, there are a few places where you have a higher chance of finding the Building 21 key, although it still requires some luck.
If you happen to be in Al Mazrah, here are some places worth checking out:
- Planes and drop boxes
- Boss supply drops
- SAM Site drops
- Legendary crates
You may have observed that certain tasks involve defeating bosses and clearing sites at the beginning.
Make sure you have the necessary equipment and a reliable group of friends before you start.
After obtaining the key, you’ll have to make your way out of Al Mazrah.
You need to select Building 21 separately from Al Mazrah. And don’t forget, this is only applicable on weekends!
DMZ Building 21 Weapon Case rewards

Teams usually head to Building 21 with the main goal of obtaining the weapon case.
To find it, they need to crack the armory safe located on the top floor of the building. Entering it, though, does require a fair amount of effort.
Once you arrive, just head downstairs to the basement and hang tight until the security doors open.
It won’t be long! Once you’re inside, just head straight for the server room and work your magic on that terminal.
Of course, you’ll have to deal with some pesky AI and operators along the way, but you’ve got this!
After it’s been hacked, you’ll find the armory door wide open and ready for you on the top floor of Building 21.
Alright, let’s start your journey upstairs, facing countless enemies along the way, until you reach the armory.
Once there, you’ll have to figure out how to crack the safe and obtain the weapon case.
Once you have it, just locate an exfil elevator, and the best loot will be all yours.
With every extraction of the weapon case, you’ll get a fresh addition to your loadout.
It’s like getting a gift every time!
