The Cabin is, as you'd expect, crammed to the rafters with genre references, among them The Shining, The Evil Dead, Cube, Hellraiser, The Blair Witch Project, the 1950s EC horror comics, Japanese horror (there's a delirious running gag about weird happenings in Kyoto), H P Lovecraft, even Michael Haneke's high-minded chiller-as-treatise Funny Games.
Sly reference is made to The Grudge and Hellraiser, to werewolves and zombies and fishmen and pretty much everything else known to go bump in the night.

The students pick up what appear to be different horror film artifacts—a dusty diary, a Hellraiser-like puzzle, etc.—and one of those items activates a relatively scary horror scenario involving killer zombies.
