The Crack of Doom is the last game in Melbourne House's series of adventure games based on Tolkien's Lord of the Rings.
The gameplay combines a text-based adventure with illustrations from the main character's perspective. Players interact with the game using text-based descriptions and a parser system to execute actions.
This is a multiple-choice adventure game based on the first book in the popular "Choose Your Own Adventure" series.
In the game, you are a kid who enters the Cave of Time to recover four items stolen by the Time Grouches and must return them to their proper places and times. The items are: a golden crown, Abraham Lincoln's hat, the Loch Ness Monster's egg, and a piece of flint.
