1st-Person Perspective

Jurassic Park: Trespasser (also known as Trespasser) is a video game, which was released in 1998 for Microsoft Windows after much hype and anticipation. The player assumes the role of Anne, the sole survivor of a plane crash on InGen's "Site B" one year after the events of The Lost World: Jurassic Park. With a fractured arm and only her wits, Anne must escape the remote island by solving puzzles and evading dangerous dinosaurs.

Trespasser's game engine was advanced for its time and required a fast computer to adequately display the game's detailed graphics without pixellation artifacts. The game disappointed many reviewers and is often mocked, but has a cult following and strong modification community to this day.


The game opens with John Hammond reading an excerpt from his memoirs. Hammond is a rich industrialist who used his wealth to assemble a scientific team which cloned dinosaurs. Intent on creating an amusement park showcasing his biological attractions, Hammond's park ultimately fails when the dinosaurs escape. While Jurassic Park was built on Isla Nublar, off the coast of Costa Rica, the animals were raised at an alternate location, Isla Sorna also named "Site B". Trespasser takes place a year after the events of The Lost World: Jurassic Park, where the general public has learned about the existence of Jurassic Park.

The game opens on a dark apartment, where mail is piling up and a phone rings. When it goes to voice-mail, a woman named Jill leaves a message, expressing amazement that Anne (the apartment's resident) had actually gone ahead on a trip to the tropics. The message closes with Jill's comment, "I thought you HATED flying."

The scene changes to an unseen person closing and bolting an airplane bathroom door and then the sounds of retching can be heard. The plane suddenly bucks and an apparent malfunction occurs and the plane crashes.

Anne awakens on the shores of an island (apparently the sole survivor of the crash), and proceeds to explore. Anne learns she is on Site B, InGen's dinosaur breeding facility. Pursued by dinosaurs, Anne makes use of weapons left behind to defend herself as she explores. Following a monorail track into the island interior, Anne encounters dinosaurs such as Brachiosaurus, Velociraptor, Stegosaurus, Triceratops, Tyrannosaurus, Parasaurolophus, and Albertosaurus. After recovering security cards from an InGen town, Anne proceeds past a dam and to a large mountain. At the summit, Anne is able to call for help. After defeating the Alpha Velociraptor and its tribe that lives atop the mountain, she is rescued by helicopter. The game closes as Anne returns to her apartment. Jill calls and the message goes to the answering machine, saying she "better have a good damn reason for not calling," Anne wordlessly responds by tossing a raptor claw on her desk.


The entire game is played through the eyes of Anne (voiced by Minnie Driver). There are only two cut scenes, one that begins the game and one that concludes the game, and an introductory video. There is occasional orchestral music, scored by Bill Brown. As she traverses the island, Anne will often talk to herself or remember clips of John Hammond's memoirs (voiced by Richard Attenborough) describing the creation (and downfall) of Jurassic Park. There are no time limits or difficulty settings to adjust and only the first level has text prompts to aid players that are new to the game.


This game features no HUD. Anne's health is represented by a heart-shaped tattoo on her breast that is filled in depending on the amount of damage she has taken; when it is completely full, and a chain appears around it, Anne is dead. Anne's health regenerates quickly over time as long as she does not take further damage. The only way for the player to know how much ammunition is left in a particular weapon is by picking up and then weighing the weapon and specifically saying things such as, "About eight shots," "Feels full," and "Hasn't been used." The actual level of realism has been debated because a number of Anne's characteristics, such as her ease at dropping items from her hand, is not very realistic. This example of not holding items is something that in real life is easy, yet difficult in the game.

I always wanted to try this game, now I have the chance. Thanks for the up.

The game plays fine, but the disk is needed to play, whether you burn it or leave it as an iso. It gets frustrating at times with the 'box stacking' in areas, and she can't seem to hold onto anything if her hand hits the wall. That doesn't make sense as she can most of the times out run a raptor, or even a T-rex, but can't hang onto a pass card if her hand hits the wall while carrying it.

This game was the Crysis of its day. There was not a single computer that would play it correctly until about 2-3 years after the games release.
