Pass Card

s are items that are randomly dropped by ghouls or centaurs. There is no place where a pass card is guaranteed to be found. A ghoul has a 1 in 80 chance of dropping a pass of either color; for a centaur the chance is about 1 in 170. The cards have no purpose.

In Fallout 1 and 2, featured Red, Blue, and Yellow Pass Keys were also used to open corresponding doors, and their presence here may be a nod to the preceding games in the series.

Note: the following is not confirmed.

These items may work as metro tickets, one for the red line and the other for the blue line, when metro Protectrons scan the player to find a ticket. The difference is that metro tickets disappear from inventory but pass cards do not. If so, having one of each in inventory implies that the player can discard metro tickets.
