Hunting Simulator (UP)

You'll more than likely get this through natural progression of the game, however, as a side note;

Originally, I was under the impression that this would come through spotting animals using a sight-enhancing item; such as binoculars - I found out that I was in mistaken in my assumption.

Instead, simply aim down the sight of your rifle and hover over an animal for a couple of seconds, when the information of the animal appears it means the game has recognised that you have "spotted" the animal.

Do this 100 times and the achievement will pop. This is a cumulative achievement and continues to count "spotting's" through both "Free Hunt" and "Campaign" modes combined.

Happy Hunting!
