Description: Shoot 15 deer in the heart
How to obtain:
Anatomy Expert, True Shot and Animal Instincts are the abilities that make it much easier to obtain this achievement, because they will let you target animals, and their hearts easily, since they are marked with an icon. The challenge is to take one accurate shot at the deer - aim the bow at the body of the animal (if you have the abovementioned abilities, the heart will always be marked with a red circle) and shoot at the heart.
There are several locations, in which you can find deer, such as Siberian Wilderness or Geothermal Valley. Be careful and do not scare them - it is best to spot them from afar (this is what the Hunter Instinct is for) and approach them listlessly, close enough to take the shot. Also, you can easily hunt for deer by exploiting the advantage of height.
