Call of Duty: Warzone has integrated with Black Ops 7’s Season 1, bringing an exciting array of new features and enhancements for players. This update not only introduces Black Ops 7’s lineup of weapons but also includes valuable quality-of-life improvements, such as enhanced character movement mechanics and the default availability of the Overkill perk. However, the centerpiece of this season is undoubtedly the new Resurgence map.
Welcome to Haven’s Hollow, nestled in the picturesque Appalachian Mountains. Players will encounter recognizable Zombies locations, including the iconic Mansion. With this new map, players can also look forward to an assortment of Easter Eggs and secrets—one notable feature being a locked room located within the Research Center.Here’s how to gain access to the Security Booth on Haven’s Hollow in Call of Duty: Warzone.
Step 1: Clean the Correct Computers in the Server Room

Begin your quest by heading to the building located at the southeastern corner of the Research Center and proceed to the first floor. Enter the server room, where you’ll find a specific server displaying a series of lights.
On this server, three lights will illuminate, each indicating different computer nodes across the floors—these are organized left to right. The bottom row corresponds to the first floor’s office area, while the upper row represents the office space on the second floor directly above.

For example, if the third node is active and red on the second row, followed by the second node on the same row and the seventh on the bottom row, you should interact with the active computer in this sequence. This means engaging with the third active computer on the second floor, then the second active computer on the same floor, and finally, the last computer on the bottom floor.
Step 2: Generate the Code for the Security Booth

After successfully cleaning the three computers in the correct order, all machines will activate. Now, move to the room accessible from the far right-hand side of the first-floor office. You’ll find a series of monitors there.
Interact with the keyboard on the desk, which will generate a unique six-digit code. This code is different for every game session; for instance, you might receive the code 898364. Be sure to write this down as it’s essential for the next step.
Step 3: Use the Generated Code to Unlock the Security Booth

Now that you have the six-digit code in hand, head over to the small building situated on the western side of the Research Center. Inside, you’ll find a locked keypad door waiting for your input.
Enter the previously generated six-digit code to unlock the door. Successfully doing this grants you access to the Security Booth, which contains a variety of rewards, including Legendary Supply Crates, guaranteed Advanced UAVs, and an Echo Unit. If this is your first time accessing the Security Booth, you’ll also receive the Error Syntax Calling Card and 4, 000 XP.
