How to Get Black Access Card and Open Black Locked Door in Building 21?
Probably the hardest locked door to access not because of its location but difficult because of its access card location. The only way to get the Black Access card is by killing the Wheelson or the Velikan, they both are bosses and are located on the 3rd floor of building 21. Velikan is the only AI enemy which uses a grenade launcher so he is easy to spot and wheelson has a distinct blue laser with a turret on wheels. They both have lots of HP so it is recommended to kill them with a squad. After killing them they can drop the Black Access card (Shown Above).
Now after finding the black access players will need to make their way to the black locked door located on the 1st floor behind the garage bathroom (shown below).
After making their way to the marked location in the above image, they will see a black door which requires the black access keycard. Simply use the access card and get the loot.
