Just Cause 3 is an open world third-person action-adventure game that is set on a fictional Mediterranean island known as Medici with Rico Rodriguez set as the protagonist. The map size is similar to that of the setting of Just Cause 2 with 400 square miles dedicated to the new setting. However its volumetric terrain has increased to allow more verticality – as a result of this: it is now possible for the player to explore subterranean caverns and to scale buildings more effectively and realistically. The world of the game is composed of five major biomes: with each having unique landmarks and landscapes.
