Spider and Web

Spider and Web is a piece of interactive fiction written by Andrew Plotkin.

Spider and Web begins innocuously enough: the player's character, an apparent tourist, has wandered into a blind alley. Upon trying to leave the alley, however, the character is confronted by a voice sneering that this is a lie and threatening dire consequences if the truth is not told. Gradually, the player pieces together that the main character is an unnamed spy who is being interrogated by an equally anonymous enemy. Through interruptions and prodding, the interrogator reveals that the spy was captured in the process of infiltrating an installation under the guise of a tourist.

Most of the commands the player gives are actually part of a story the character is telling to the interrogator. Any part of the story that the interrogator disputes is challenged; the player is executed after a number of these "challenges". Thus, the player's main goal is to tell the captors a plausible story to explain what they already know (or more precisely, what they think they already know).

Like many of Plotkin's works of interactive fiction, Spider and Web is known for its high level of difficulty. This is due in part to the use of rapid-fire switching between past and present, between fiction and truth; an additional factor is the game's abrupt start with no explanation. Novice players may quit in frustration long before piecing together the plot.
