Hints & Tips

When you are hunting and you see something scurry, hop, or run by, shoot at it. It will let out a small squeal and die.

Killing deer using a bow
This trick is really useful when you are playing a season and are required to use a bow to hunt a high point deer that keeps running away. Obtain a gun with a scope. Then aim in front of or at the deer depending on how it is moving). Switch to the bow and do not move your hunter. Aim with your bow and shoot. This same thing can be done at the target range.

Kill a raccoon
Walk by water and walk around until you see a raccoon. Then aim and shoot it. Note: You will not be able to claim it.
