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.
Here's a dramatic view from atop the waterfall that the kids jumped off of while running from the Indestructible Rex in Jurassic World. The river leading to the falls is currently running dry due to the spring where it begins being blocked off, though the pool at the base remains for the most part. You can also see the different fogging that is a side effect of time-of-day; everything is slightly darker and foggier, though I think it actually captures the atmosphere of the movie even better than before.
Yeah looks nice :D
