Warzone DMZ Key: Where To Find DRC Building 21 Access Card

To get this artifact, you must first discover a site known as “The Quarry ,” which is hidden in an underground tunnel system near Verdansk Airport. Once there, go down a hallway towards the Crane Control Room – a huge yellow structure with a large green circle on it – this is DRC Building 21.. You must then enter via one of its two doors and look for an orange access card on one of its workstations. You’ll be able to move farther in Warzone and access new places after you’ve earned the card.
