Isla Nublar, the setting for Jurassic Park films, was largely destroyed by a volcanic eruption. Many dinosaurs and some of the research results could not be recovered while people were escaping this disaster. Now in Rückkehr zur Isla Nublar ("Return to Isla Nubar"), a small brave group is trying to save what can be saved. To do this, the players set up new observation posts to secure existing knowledge. The dinosaurs, in turn, are trying to save their own lives and (understandably) they have little leniency for the players' efforts.
