Just Cause 3 is an action-adventure game, played from a third-person perspective. It is set in an open worldenvironment 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 â€“ 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 â€“ the grappling hook and parachute â€“ 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. Other game mechanics have been overhauled and updated. For example, Rico has the ability to attach and tether multiple objects together with his grappling hook,with the amount of tethers available increase by activating in-game 'mods', earned by completing challenges. Parachuting is also more stable and allows players to shoot enemies from the air.The player can grapple to every object and non-playable character in the game, with the use of the grappling hook.In-game currency has been left out of Just Cause 3, making the series' supply drops more easily accessible and imaginative for the player. However, this affects difficulty; for example, if the player chooses to ride a tank, the enemy AI matches the power of it and adopts weapons that are able to take down a tank.Another new feature is giving the character infinite C4. The C4 can be placed free over the world by the player but only three at a time, though by using the in-game featured 'mods', up to five can be deployed. Unlike previous installments that required players to purchase C4, Just Cause 3 instates this weapon to allow for more chaos.In Just Cause 2players were able to stand on top of moving vehicles but only in the center; players are allowed to move around on vehicles freely in Just Cause 3.Players are expected to liberate hostile military bases and towns featured in the game, and they will act as fast travel locations thereafter. Creativity and destruction are heavily emphasized in Just Cause 3, with many things in the game, including structures like bridges and statues, providing a variety of ways to be destroyed. A new mechanic called Rebel Drop was introduced. It allows the player to pause the game to select equipment, weapons, and vehicles through a pause menu. The selected objects are dropped into the game's world and can be used by players.The game also features Challenge Modes. It includes mini-games like wingsuit races and the destruction frenzy mode, in which new objectives and challenges are unlocked when the player destroys an enemy base. Despite the multiplayer mod of Just Cause 2 being well received by players, the game only featured asynchronous multiplayer, in which challenges and leaderboards were included instead of any cooperative or competitive multiplayer mode, as the studio wanted to focus their manpower, time and resources in creating the game's world.
