The easiest way to get kills is to remain idle until your hunting partner says something similar to 'Did you hear something in the bushes?' If you then wait another five minutes the crosshairs should appear and you will be able to shoot the animal that you are hunting. Another way to make easy kills is to go to your hunting location and use the correct animal call a few of times until you hear a strange sound. Use the animal call again and look around and see if the crosshairs appear. Keep repeating this process until you kill an animal.
