All challenges complete.

Throughout the course of the game, you might notice upon experimentation and exploration that there are several different challenges within each region of the island. In total, there are 13 challenges you must complete for this achievement.

A bulk of these challenges require hunting down and either shooting, collecting, or burning a set amount of items that are unique to their location on the island. Such items range from shooting mines to collecting egg and burning banners.

Most of these items for each challenge are very well-hidden around the island, so it is in your best interest to follow the guide embedded within the link below in order to save you a lot of trouble.
