Creator/{{Infocom}}'s 1987 entry into the horror genre opens in the computer lab at G.U.E. Tech. You've braved a snowstorm to finish an important assignment, but find your work interrupted by strange nightmares. When your paper vanishes from the server you find yourself exploring the campus for answers.

''The Lurking Horror'' is one of Infocom's easier [[InteractiveFiction text adventures]], but has some very creative puzzles and great writing and atmosphere.

!!This game contains examples of:
* BlobMonster
* ClosedCircle: You're forced to spend the night in the computer lab by a blizzard.
* CopyProtection: Your user name and password.
* {{Expy}}: G.U.E. Tech for the Massachusetts Institute of Technology.
* {{Feelies}}: Your student ID card and a little rubber centipede.
* HaveANiceDeath: [[AvertedTrope Averted]], surprisingly for the usually [[WorldOfSnark snarky]] Infocom.
* LovecraftLite: The monsters are terrifying, but for all the Lovecraftian trappings it's more general horror than a CosmicHorrorStory.
* MadScientist: [[spoiler: If you consider alchemy a science.]]
* MoonLogicPuzzle: The maze at the bottom of the tunnels.
* MundaneUtility: The disembodied hand. And how.
* NightmareSequence / OrWasItADream
* SummoningRitual
* ThingsThatGoBumpInTheNight: The final monster you face is described in these terms.
* TimeMarchesOn: Much of the premise relies on 1980s computer networking technology, enough so that at times the game feels like a PeriodPiece.
* UnwinnableByDesign: Generally falls under Tough on Zarf's scale.
