The safehouse in Call of Duty: Black Ops 6 presents a series of puzzles players must solve to unlock a safe containing a valuable melee weapon blueprint and a hefty sum of in-game currency. The first puzzle is shown when you enter the home in the puzzle room. This will lead to the basement generator puzzle, which opens the door to a keypad. From there, you pick a door’s lock, find a key in a meat room, and end up in a radio room. That radio room gives you the final number to unlock the safe.
