Return to Jurassic Park is a mod for the 1998 PC game "Trespasser" set on Isla Nublar several years after the events of the first film. Running on an upgraded Trespasser engine, players will get to explore the abandoned facilities through nine expansive levels covering the entire island, while at the same time searching for weapons and supplies as well as solving challenging puzzles; encounter a wide range of dinosaurs, from the tiny compsognathus to the massive aquatic tylosaurus; and uncover a story unlike any previously presented in a Trespasser mod.
Even at the outer edges of the abandoned safari park, nature has begun to overwhelm much of the man-made construction. Clusters of palms and bushes make up the lower layers of the jungle while the taller plants struggle for a glimpse of the sun high up in the canopy.
