Feelies
All of Infocom's game packages since Deadline included extra content in their game packages called "feelies". The feelies for The Lurking Horror included:
- A Student ID Card
- "G.U.E. at a Glance", a guide for freshmen of the school, including maps of the campus and buildings and background information on the school
- A rubber centipede-like creature reminiscent of one of the monsters in the game. This was not mentioned on the package, and made for a creepy moment even before the user played the game.
