Just Cause 3 is an action-adventure game played from a third-person perspective. It is set in an open world environment of a fictional Mediterranean island known as Medici with Rico Rodriguez set as the protagonist. The world size is 400 square miles (1,000 km2), similar to that of the setting of Just Cause 2.However, its volumetric terrain has increased to allow more verticality – as a result of this, it is possible for the player to explore subterranean caverns and to scale buildings more effectively and realistically.The game’s world is composed of five major biomes, with each having unique landmarks and landscapes.
A variety of tools are provided to players for traversal in the game. Just Cause 2‘s signature features – the grappling hook and parachute – re-appear with improved mechanics. The focus on chaos and exaggerated physics also remain. A new wingsuit, which is permanently equipped by Rico, is featured in the game and allows the player to glide across the world in a much faster way. When the player almost reaches the ground while using the wingsuit, they can draw themselves back up in the air by using grapples. Players can switch between using the parachute and wingsuit freely. In addition to the equipment provided, a wide range of weapons, like missile launchers and shotgun RPGs, and vehicles, such as fighter aircraft, planes, ships, and exotic cars, are included in the game. These vehicles can be customized by the player and can be used as weapons.
