Paper Trail is a site that is centered around Infamous: Second Son. Its purpose is to have a series of mini-games released on a weekly basis which eventually leads to free DLC for people who participate in the events.
As of December 16, 2018, the website is no longer active, but the in-game missions are still playable.
Paper Trail began a week before the release of Second Son and launched a series of quizzes that would, by the time Second Son came out, be used to start a small series of events inside the game.
By completing each "episode" the player would gain Karmic points which track the player's progress throughout the event game.
