Far Cry 4 for the PS4 starts in South Kyrat, and is free to explore almost immediately, but can only unlock North Kyrat over the course of the story. The map is progressively opened up by liberating bell towers, freeing them from Pagan Min's influence and allowing the Golden Path to expand. The player will also encounter outposts, or enemy checkpoints that need to be captured by eliminating all soldiers. Four larger outposts, or fortresses, can also be found, featuring stronger defences and more difficult combinations of enemies. Liberating bell towers and clearing outposts will unlock further side-quests including escort missions, hostage rescues, bomb disposal quests, and hunting missions.
The ps4 game also offers a co-operative mode in which a player joins another to assist in various missions. The game follows Ajay Ghale, a young Kyrati-American of Nepali origin who returns to his native country of Kyrat to spread his deceased mother's ashes. Kyrat was once an autonomous state in the Himalayas ruled by a royal family before a series of perpetual civil wars. Ajay finds the country in a state of conflict between Kyrat's Royal Army led by the country's eccentric and tyrannical king Pagan Min and the Golden Path, a rebel movement fighting to free Kyrat from Min's oppressive rule. The choices Ajay makes will determine the fate of Kyrat. After the death of his mother Ishwari, Ajay returns to his home country of Kyrat.
In the twenty years since Ishwari and Ajay fled Kyrat, the rebellion has stagnated, with the Golden Path fighting for their very existence. As the son of Mohan Ghale, Ajay becomes a symbol for the Golden Path to rally around, and after freeing a group of hostages and liberating territory held by Pagan, they plan on breaking Pagan's stranglehold on power by targeting his three regional governors: Paul Harmon, who oversees opium production and runs Pagan's torture chambers; Noore Najjar, who runs poaching and prostitution rings and is herself a victim of Pagan's cruelty after he kidnapped her family; and Yuma Lau, Min's adopted sister and trusted general who is obsessed with uncovering the secrets of the mystical realm of Shangri-La.
