Passenger Manifest

The Passenger Manifest is an item added in v0.28. It is part of the story and is used for tracking the Get Closure achievement.

Gameplay
The passenger manifest allows the player to find and catalogue the 45 passengers that were aboard the plane before the crash. When the player finds a passenger, he will be alerted to the seat number, a writing sound is played, and the manifest is updated. The name will also be crossed off the passenger manifest. The finding of passengers and the passenger manifest has been heavily bugged for most of the games life. Though it may have been fixed properly in patch v0.68.

Finding all the passengers is also an achievement, called Get Closure. More information about finding the passengers can be found on that page.
