Events are one-time use cards for the Runner. An event is immediately resolved and then trashed after being played. The Runner can play an event from Grip as an action during the Action Phase, spending Click and the play cost of the event in credits.

Events represent singular occurrences and are always trashed after being played.

The Runner pays credits equal to the play cost of an event to play it. When played, an event's abilities as listed in its text box are resolved. Then, the event is immediately trashed. Events are never installed.

Playing Events

For Click, the Runner plays an event from his hand by paying its play cost. He then places it faceup in his play area, immediately resolves the effects of the event, and trashes it.
