Rook Islands is an open world in which players can explore freely. Each skill tree upgrades different aspects of Jason's abilities, with the Spider upgrading his stealth takedowns and hunting skills, the Shark upgrading assault takedowns and health, and the Heron upgrading his long-range takedowns and mobility.As skills are collected, a tribal tattoo on Jason's forearm grows correspondingly. Skills are collected by gaining experience from completing missions and killing enemies, and are unlocked in three skill trees, themed as the Spider, the Heron, and the Shark. For instance, players can scout an enemy's outpost by using a camera to mark the locations of enemies, or toss rocks to distract enemies.The stealth approach, which can be done by using silenced weapons and combat knives, can prevent enemies from triggering alarms which call for reinforcements. Alternatively, players can utilize stealth to avoid the attention of enemies. They can kill enemies by utilizing firearms such as assault rifles, sniper rifles, grenade launchers, rocket launchers, and explosives like land mines and grenades. Players portray Jason Brody and can approach missions and objectives in a variety of ways. Far Cry 3 is a first-person shooter set on the fictional Rook Islands, a tropical archipelago controlled by bandits and pirates.
