There are 21 Treasure Hunts in Far Cry 6. The treasure hunts provide access to a variety of one-of-a-kind weapons required for the Armed to the Teeth trophy or achievement. Treasure hunts are generally small puzzle areas where you must complete a series of steps to gain access to a treasure chest.
There are no pre-requisites for Treasure Hunts. A player just needs to head the purple-colored treasure hunt icon and need to read the note that starts the treasure hunt.
