News - Warzone 2 Dmz. New Building 21 Update. All Key Card Door Locations

Intro

Activate the bell icon, .

Blue access card - transition room (1st floor)

The first card is the blue access card. The blue door is located in the first basement floor across from the data center in the transition room; it's possible to run straight there once you spawn in, but each one of these locked rooms contains three to four gold crates, so that's what's inside.

Sam sites shoot down a supply drop, and the blue access cards can be found in it.

Green access card - garage (1st floor)

The second card is the green access card; it's a rare card because you can only get it from a safe in Building 21. There are two areas with green doors: one is in the garage, and the other is in the room down the hall. A few green doors are found.

Black access card - garage bathroom (1st floor)

In there, the third card is the black access card; it's the most rare because you have to beat a boss called Velikin, who spawns when there are only four minutes left on the clock. He'll drop the exclusive RG-LE80 launcher that's only available in Building 21, so you'll want to X-fill with it, and he'll drop the black access card, which you'll likely want to X-fill first and then come back since the black door is located in the first basement floor across from the garage bathroom, now there's four spawn points on the first floor so you got a really good chance to spawn near the black door and for the most part, that's all the hidden doors that are locked on the first floor, so, on this floor there is the blue door there's the green doors and then there's the black door.

And at first, it does seem like a lot, but the more you can kind of visualize where these are located, it gets easier.

Red access card - additional office (2nd floor)

Let's move to the second floor of building 21 now. We're going to now focus on the "red door," the red access card. The top half of the floor is full of offices, and in the area called "additional offices" in the middle is the red door.

That's the last door, the fourth door, which requires an access card just like the blue card. It's found in supply drops on Al Mazura. The Red Door is the best part of the second floor. Not much else is going on.

Armory room (3rd floor)

So let's go ahead and move to the third floor. The third floor is where we find the armory room with the weapons case, the moving mobile enemy turret, and the Valken boss fight at 11 minutes. You'll notice the security system can get hacked in the data center on the first floor, which unlocks the armory room on the third floor.

The safe cracker inside contains the weapon case and a green access card. I've never killed the turret yet, but besides the turret, there is the Vulcan boss on this floor, so I can better understand what's happening with your time limit. At 11 minutes, that's when the security locks deactivate on all floors; you can go ahead and hack the data center now.

At seven minutes, the Expo location spawns in, so locate the x-fills at that time if you have the weapon case; you don't want to wait until seven minutes. And then, at four minutes, you have the Vulcan boss that shows up on the third floor, and he's got that RG-80 launcher, and he's holding the black access card, so you're going to want to be able to take him down within the last four minutes and go ahead and exfil with that stuff, and , you may know this already, but there are three players on each team; there are four teams in Building 21, which means there are nine other players coming against you.

Building 21 dlc update

But Building 21 was only live for 24 hours on launch, and Infinity Ward took it down for three days. I imagine it's because the Building 21 access card had unlimited uses. I wouldn't doubt that gets patched and is the reason for the downtime. Now the glitches for the DMZ won't be as spectacular as the infinite money glitch anymore, but we still have a lot to look forward to with other DLC content coming and more faction missions.

With only Legion White Lotus and Black Mouse, you'd think there'd be more added in the future, but I'm looking forward to it. I'm enjoying the faction missions; they're keeping me busy.

Thanks for watching, subscribe!

I'm having a real good time with the DMZ, and I hope you are too. I hope this article helped; see in the next one.
