Hunting: Clearing the grounds | Activities Far Cry 4 Guide

At the spot, you can replenish your ammo.

This kind of missions consist in clearing the grounds of animals, tasked to you by individual villagers. It is a good idea to get a decent weapon and hunting syringes.

There are quite a few animals to kill, try to eliminate them as fast as possible, e.g. with explosives.

After you replenish your supplies in a given area, go to one of the small hunting ground. There, within a small area, there are several animals herded together. You need to eliminate all of them, which you are informed about, by the yellow bar in the middle of the screen. The fastest way to do this is to pepper the animals with grenades and finish your job with a shotgun, or other weapon (an LMG, for example). After you are done here, get to another hunting ground and do the same. Killing all of the animals in a given area ends the mission. After you complete two such mission, you receive a signature weapon - HS77.

To complete the game in 100% you need to complete 4 such missions.
