The universal code required to open the primary vault doors of Bunker 10 is 60274513. Unlike RNG-based puzzles scattered across subsequent seasons, this eight-digit sequence remains constant for this installation.
Executing the unlock requires strict mechanical discipline:
Approach the keypad mounted to the right of the sealed blast doors. Hold your interact key to bring up the numerical pad. Punch in 6-0-2-7-4-5-1-3. You will hear an audible confirmation chime, followed by the clanking mechanical release of the inner vault gears. The heavy steel doors slide outward slowly over roughly four seconds, broadcasting an echoing acoustic cue across a 150-meter radius.
Keep your sidearm or shotgun raised while the doors cycle open. Enemy squads frequently lurk in the surrounding foliage, waiting for unsuspecting players to punch in the sequence before initiating an ambush.
