For a crippled that’s inactive technically successful beta, Call of Duty’s DMZ definite has been 1 hellhole of a amusive experience. DMZ’s latest twist concerns a caller playable country selectable erstwhile loading into DMZ—but you’ll request a keycard to get in. You tin find keycards for this caller country passim Al Mazrah. So, privation one? Worry not: This usher volition screen a fewer communal ways you tin find Building 21 keys arsenic good arsenic however to enactment live agelong capable to successfully flight with one.

DMZ is simply a PvPvE extraction-based crippled mode that’s caller to Warzone 2.0.

Where to look for Building 21 Keycards

Like different cogwheel successful DMZ, Building 21 keycards are randomly distributed. But you tin prioritize definite locations to summation your chances of uncovering one.

For now, overmuch of what follows is based connected hearsay and documented examples connected the internet. r/DMZ is simply a large spot to support up connected discoveries successful this mode (and volition apt beryllium 1 of the archetypal places players volition commencement reporting the find of an introduction constituent to Building 21). As a note: You tin lone store 20 keycards successful your stash astatine immoderate fixed time. So if you’ve been stocking different keys for random locations, you mightiness request to usage those up earlier aiming to find a Building 21 keycard. There look to beryllium 3 kinds of Building 21 keycards, the “Blue Access Card,” the “Red Access Card,” and 1 called “DRC Building 21 Access.” These look to travel successful “used” and “worn” varieties, though the meaning of that isn’t known close now. Based connected however different keys enactment successful DMZ, it’s harmless to presume this indicates however galore uses you’ll get retired of a key.

Players are besides discovering notes with ultra-cryptic hints astir Building 21’s location. No one’s been capable to marque heads oregon tails of these yet.

Red and orangish loot caches, though rare, look to beryllium a bully root of keycards. The accidental of 1 containing a keycard is wholly up to RNG, however. You tin find these caches, usually, successful Strongholds, Fortresses, and connected the bid that moves astir the map. These are unsafe locations, truthful beryllium connected your guard. If you get fortunate and find 1 connected archetypal effort and without overmuch of a firefight, it’s clip to get the hellhole retired of Dodge to stash that cardinal successful your inventory.

Random proviso drops tin incorporate keycards, too. These spawn randomly (you’ll perceive an announcement that a proviso driblet is connected its way—as volition each different subordinate you’re competing against). But you tin besides trigger 1 by capturing a SAM site.

Speaking of which, if you person the faction ngo asking you to seizure a SAM tract and loot a proviso cache it shoots down, you tin perchance kill 2 pigs with 1 stone here. DMZ is often astir uncovering opportunities to instrumentality retired aggregate objectives astatine once.

Supply caches changeable down by SAM launchers tin incorporate Building 21 keycards.. Unlike loot caches and different proviso drops, capturing a SAM tract and causing a proviso cache to autumn from a level is thing you person a spot much bureau over. It’s not a atrocious docket to acceptable erstwhile loading into the DMZ.

The commander’s chopper seems to person Building 21 keycards. As each DMZ players know, astatine random times and locations, a precise lethal and assertive chopper volition spawn in, loudly announcing that you request to permission the country and that it volition occurrence connected anyone it spots (god assistance you if it does). If it’s wrong a captured SAM launcher’s range, oregon if you person the close equipment, you tin instrumentality it down and loot the remains. The RAPP H is simply a large LMG for this—and you tin load it up with anti-armor munitions if you person that connected manus (you tin prime it arsenic a portion of your Field Upgrade erstwhile loading in). Bots besides commonly transportation astir rocket-propelled grenades, peculiarly bots which patrol tiny villages.

DMZ: How To Stay Alive While Hunting Building 21 Keycards

DMZ is unpredictable. Setting retired with a circumstantial docket successful caput is smart, but you tin ne'er archer what the random operation of loot, bots, and players volition bring. Here are immoderate wide tips if you’re heading retired successful hunt of keycards for Building 21.

When loading into DMZ, prime immoderate weapons you’re comfy with but marque definite you oregon your squad has immoderate operation of the following:

Tactical Equipment: Spotter Scope oregon Heartbeat Sensor

Lethal Equipment: Proximity Mine oregon Claymore

Field Upgrade: Recon Drone, Munitions Box, Portable Radar, oregon Anti-Armor Munitions Box (if you’re readying to instrumentality down the commander’s helicopter)

My idiosyncratic loadout ever has a Spotter Scope, Recon Drone, and Claymore, but immoderate operation of the supra volition enactment for you. And if you’re going successful with 2 friends, you tin beauteous overmuch screen each these bases oregon person immoderate country to get experimental.

Because the DMZ is truthful deadly, you request to prioritize your quality to get to the extraction constituent if you privation to get retired with a Building 21 keycard. Toward that end, present are immoderate dos and don’ts:

Do: Approach each determination with implicit caution. This is wherever Spotter Scopes and Heartbeat Sensors travel successful handy: Maintain a region from each spot that could beryllium remotely occupied and usage your Spotter Scope to cheque an country for opposition. You should never, ever, spell into a fixed country unsighted successful DMZ.

Do: Get the hellhole retired of determination the 2nd you find a keycard. Sure, that intel declaration looks precise tempting. Or possibly you’ve recovered a harmless to crack. Forget it. A Building 21 keycard is what you’re present for, and erstwhile you get it, your precedence becomes extracting it safely. Getting retired of the DMZ is simply a ngo unto itself. Bots mightiness beryllium patrolling the area. Exfil campers (re: different players) mightiness beryllium scoping the area. Approach with caution. Send 1 idiosyncratic successful to telephone successful the chopper; retreat to information and contention to committee it the 2nd it’s wrong climbable distance. Never fto your defender down until you’re safely successful the air.

Do: Search each aesculapian kit you see. Since the astir caller update, DMZ has much Self-Revive kits and revive pistols. You tin find these successful a assortment of places, but they’re astir often successful the quadrate aesculapian boxes you find mounted to assorted walls. Having a self-revive kit tin mean the quality betwixt getting retired with a keycard and losing each your stuff.

Do: Acquire an armored conveyance if you can. Sometimes you’ll request to contention crossed the representation to deed an extraction constituent (the 25 minutes DMZ gives you to execute each your tasks volition evaporate earlier you cognize it). Armored vehicles aren’t invincible and you tin instrumentality harm from inside, but they fare a hellhole of a batch amended than the game’s different rides.

Don’t: Take connected contracts, hack UAV towers, oregon effort to decorativeness objectives different than searching for keycards. You’re present to find a Building 21 keycard. That means you person 2 objectives: Find a card, and exfiltrate. Although a completed declaration is indispensable to get an exfil streak and a perk, it mightiness not beryllium worthy the hazard if you’re conscionable hunting a keycard.

Don’t: Shoot anyone (players oregon bots) unless changeable at. Ammo and armor tin tally retired accelerated if you’re not careful, and firefights with immoderate absorption successful the DMZ tin crook into a resonance cascade shitshow of non-stop warring that volition extremity with your decease and the nonaccomplishment of each the loot you’ve gathered.

Don’t: Stay connected the bid for precise long. Yes, that bid has large loot (possibly adjacent keycards) but you’re connected borrowed clip each 2nd spent onboard. It’s a elephantine beacon for different players to find large equipment, and bots volition unfastened occurrence connected it with wall-piercing rounds the 2nd they fishy you’re present.

No one’s wholly definite what awaits successful Building 21, but having a enigma similar this to pursuit successful a remarkably unpredictable mode similar DMZ is beauteous exciting. Good luck scoring those keycards.
