Far Cry 3 Classic Edition

After liberating an Outpost, these will become available to you via the news board in the same Outpost. The Path of the Hunter quests are shown to you via a Blue Dear icon. These are small side quests that task you with killing a certain animal with a specific weapon.

Accept the mission, and you'll then be directed to pick up the weapon at a set location and from there, you'll need to use it to kill the animal. Killing the animal and then skinning it will result in you completing the mission.
