What is Navcard?
The Navcard is an item in TranZit, Die Rise, and Buried in Call of Duty: Black Ops II Zombies mode. The primary use of the navcards and the NAVtables is to join all three radio masts in each map (TranZit, Die Rise, and Buried) and activate the button in Buried that completes each separate side to the story.
