Pass Card

In Fallout 3, 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 are accepted by Protectrons in lieu of metro tickets in specific areas.

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.
