Although Trespasser was promoted as "the digital sequel to The Lost World," various factors, such as the budget for purchasing licenses or parallel development with the film, caused that it did not entirely fit into film continuity and canon. Some changes were made in dinosaur designs, locations, and the shape of Isla Sorna, where the game takes place. The course of some events did not escape the changes either. Since the interconnection between the individual media under the Jurassic Park / World brand is not as tight as, for example, in the case of Star Wars, the world of Trespasser is built from three primary sources, which are:
- films Jurassic Park (1993) and The Lost World: Jurassic Park (1997) directed by Steven Spielberg
- novels Jurassic Park (1990) and The Lost World: Jurassic Park (1995) by Michael Crichton
- original content added by the developers of the game
However, even within the Trespasser itself, it was not so easy or so simple as it appeared. Due to complications and the hurried development of the game, audio files containing, among other things, information about historical events of Trespasser remained unused or were deleted. Information on the existence of files with this data, together with other similarly oriented materials, comes from the following currently known sources:
- files of the final and development versions of the game
- The Official Strategy Guide
- design documents (Walktrough, Hammond Numbers, ANNE SELECTIONS)
- the original script of Hammond's voiceovers
Some of these sources partially overlap, others are completely unique. The timeline below is a compilation of information from all known sources.
