Novel
A novel based on the game was also written by Alan Dean Foster, who is famous for having written book versions of many famous movie titles such as Star Wars (ghostwriter), Alien, Aliens and Alien³.
The novel is not completely consistent with the game, but presents the point of view of the indigenous civilizational race, something not seen in the game. The novel also provides some background detail (such as the reaction on Earth after the discovery of Attila), in addition to filling several plot holes and mysteries that cannot be explained in the game.
An audio book version of the novel was also released. Notably, the cover of The Dig audio book features a picture of four astronauts. The artwork was done for the second draft of the game which featured four game characters. Later, the artwork was retouched for the game box and the book covers to reflect the reduction to three main characters, but the cover of the audio book was left with the four character design.
