Bad Publicity: A token acquired by the Corporation that provides the Runner with 1 to spend each run.
Bad publicity is a token the Corporation can acquire through various cards and effects that provides extra revenue for the Runner during runs. The Runner gains 1 at the start of every run for each bad publicity that the Corporation has, which is returned to the credit bank if unspent by the end of the run.
Some cards and events in Android: Netrunner give the Corporation bad publicity. For each point of bad publicity the Corporation has, the Runner gains 1 at the beginning of each run. The Runner may spend these credits during his run as if they were in his credit pool, but any unspent bad publicity credits return to the bank at the end of the run. Bad publicity always generates revenue for the Runner at the beginning of a run, even when the Runner makes multiple runs in a single turn.
Because bad publicity credits are only gained at the start of a run, the Runner does not immediately gain credits from bad publicity the Corporation may acquire during a run (such as by rezzing a piece of Illicitice).
