The Call of Duty: Black Ops Cold War beta is over, but that didn't stop one intrepid fan from discovering a fantastic Easter egg hidden within its menu screen.
Redditor Neur0r took a close look at the background images of the beta menu screen, taking screenshots and analysing them in Photoshop. It's hard to tell, but there are numbers displayed on the images for each mode as well as the store. These numbers, alongside the CIA stamp, sparked a thought in Neur0r's mind.
As revealed in a post on the Black Ops Cold War subreddit, Neur0r ran these numbers through the CIA's website, specifically the section that lets you search through declassified documents from the Freedom of Information Act. Neur0r discovered the faint numbers on the menu pull up period-correct documents.
