The Addington's Dangerous Game

The Addington's Dangerous Game is a holotape

Location
The tape can be found in the basement of Black Bear Lodge, on a stereo next to some assorted storage.

Behind the scenes
The title of this holotape, in addition to Westley's proposal, references "The Most Dangerous Game," a short story by Richard Connell in which the protagonist is stranded on a Caribbean island, where he is hunted by an aristocratic big game hunter.
