Start a new game. After the first cutscene, when you are instructed to explore the mansion, remain where you are for approximately ten minutes. An alternate ending should then play out for you.
Armed Escort mission locations
Armed Escort missions involve driving a supply truck through multiple enemy waves. They can be found at the indicated coordinates.
At the very start of the game, once you can free roam, first unlock all the radio towers and do not use any vehicles. Doing this will naturally get you everything you need to upgrade your items, earn more money, and obtain free weapons. Make sure to loot everyone you kill and sell their items. Additionally, do side missions before doing the primary missions (for example, armed escorts, fashion week, etc.). The better head start you can get on your character before doing the primary missions, the easier and more fun the game will be.
Eye For An Eye quest locations
Travel to the indicated coordinates to find the corresponding quest. You must kill the enemy commanders with a specific weapon, then take a photograph as proof.
Travel to the indicated coordinates to find the corresponding hostage rescue quest. Most of the quests become available from liberated outposts. They are different from the karma events of the same name and only provide experience and money.
Travel to the Clouded Leopard marker on your map that is southwest from the Kyra Tea Factory location, and just across the river. This area can be accessed at the start of the game. It is recommended to use the Recurve Bow, but you can use any bow or weapon. However, you are rewarded with double skins for each kill when using a bow. Use this method to quickly earn enough money to upgrade to the Recurve Bow if you do not already have it. Throw bait down from the hill, then shoot the Clouded Leopard in the head. Repeat this process until you are out of bait. Then, go down to skin the animals to refill your bait. Repeat this process as many times as desired. Clouded Leopard skins sell for 16,000 rupees each. It is recommended to upgrade the bait bag first to make the process quicker. You can easily earn 500,000 rupees approximately every ten minutes. You can also use this same method at any predator location (bears, bengal tigers) to quickly increase your Karma meter.
Infinite money
After completing the first quest in the Ghale Homestead and unlocking it, you can purchase a farm upgrade for a large amount of rupees. Buy it, then unlock the first level perk on the Elephant path to get double ingredients every time you harvest a plant. Once the garden appears, pick all the plants, then fast travel to an outpost to sell the plants. Fast travel back to the homestead, and the garden will be fully restocked with valuable plants. Repeat this process as many times as desired.
During the final mission, before entering the palace to confront Pagan Min, equip the rocket launcher. You can find multiple rocket launchers during the final battle in the fortress. When Ajay Ghale points his pistol at Pagan Min's head, do not shoot. You will then fly in a helicopter to a burial site with Pagan Min, and Ajay will lay the ashes of his mother. After exiting the tomb, Pagan Min will escape in his helicopter. Once you are back in control, quickly shoot down the helicopter with the rocket launcher. It will crash into the ground below. Travel down the mountain, and destroy the wooden doors with an explosive. You will find the crash site up the path, and Pagan Min's body nearby. Loot his body to get Pagan Min's Golden Pen (worth 300,000 rupees), Lapel Pin #2 (worth 350,000 rupees), and 250,000 rupees. Then, fast travel to anywhere nearby, and return to his body to be able to loot him again. All items respawn after each fast travel. Repeat this process as many times as desired. You can easily get 1,800,000 rupees approximately every ten minutes. Note: This glitch was performed on an unpatched version of the game.
Infinite XP
First, successfully complete the game, and unlock the "Death From Above" and "Heavy Takedown" skills in the Tiger path, to easily earn an infinite amount of XP in Pagan Min's fortress located in northern Kyrat. Once the fortress is weakened, sneak through the front doors by using the steps to the left of the main gate and taking down the heavy soldier. Cross the wooden bridge, kill the rooftop soldier, and use the Death From Above takedown on the remaining heavy soldier. Once they have all been defeated, pause the game, and select the "Save" option. Then, allow the remaining snipers and soldiers to kill you. Throw C4, grenades, or fire rockets at your feet to speed up the process. You will respawn right outside the fortress' front doors. Repeat this process as many times as desired to earn an unlimited amount of XP to unlock the remaining skills.
Infinite XP and money
Enter the "Shanath Training Ground" outpost from the east. Immediately when you enter the outpost, you will see a heavy armored enemy patrolling the bridge. Kill the heavy armord enemy with C4 to get 240 XP. Then, kill the two tigers below, and skin them as quickly as possible (the tiger skins can be sold for 7,000 rupees each). Once you are finished skinning the tigers, pause the game and save, then intentionally die. You will spawn around 320m away from the outpost with the XP you got from the enemies and the skins you got from the tigers. Run back to the outpost, and repeat the process. When you die again, you will respawn next to the outpost. Repeat this process until you can obtain the "Heavy Takedown" skill. Then, instead of killing the heavy armored enemy with C4, sneak up on him, and kill him with the "Heavy Takedown" skill to get 400 XP per kill. Repeat this process as many times as desired. Note: You do not have to worry about getting more C4, as you will get an extra C4 after each death.
Mani Wheel locations
Travel to the indicated coordinates to find a Mani Wheel that can be spun.
Green plants (for health regeneration) are rarer in Far Cry 4 than its predecessors. Do not miss an opportunity to overstock them, as they are very useful with the fortresses and other difficult missions and objectives.
Post-Ending Cutscenes
After completing the game you will be allowed to explore Kyrat once more to complete the remainder of the content, this will also unlock an optional scene that varies according to who you sided with near the game's ending. If you were loyal to Amita, you can enter Tithra for a scene. If you sided with Sabal, return to the Temple for a scene.
Propaganda Center mission locations
There are four Propaganda Centers in and around the Abandoned Jheel at the indicated coordinates. To complete the missions, eliminate the enemies then destroy all the propaganda equipment at that location. Buildings with propaganda equipment are marked as yellow on the map.

Supply drop quest locations
Travel to the indicated coordinates to find a supply drop quest. You will receive the quests through a radio transmission. They involve collecting supplies and dropping them off at a different location. All of the quests are timed. Most of the quests are located inside small huts at the base of radio towers.
Use a weak weapon to inflict the first hit on an animal, then finish it off using more powerful methods to get an undamaged hide.
Undamaged Hides
The weapon that you use to inflict initial damage on an animal you are hunting will determine what sort of reward you receive upon killing it. Therefore, it's a good idea to start with a standard shot if you want a nice skin, even if you finish off the critter using a grenade.
