One year after the events of the Jurassic Park movie, John Hammand wants to bring Jurassic Park back online. He has sent a team of heavy armed experts down to the park to "clean everything up" so to speak. Now, Biosyn Corp (the company that tried to steal the embryos from the movie) is back to take control of the park for themselves. John has sent Dr. Grant down to the park (because he is familiar with the place) and teamed him up with Tactical Sergeant Michael Wolfskin. In the game, you play as Alan Grant (the second player is Michael Wolfskin) and you try to get the park back online and in doing so, you take down Biosyn Corp. and take some dinosaurs down as well with 6 (7 eventully) weapons.
