Big Buck Hunter

This needs to be done in Classic mode, which is accessed via the arcade machine in the cabin. In order to unlock this machine, you need to finish an adventure in the main game mode. Once the machine is accessed, select "1 trek". You can select any trek you want, but I suggest Whitetail Deer, and then Keyser. The accuracy refers not to shots, but to kills. So hitting a buck three times will only give 33% accuracy. It is kills that you need. Now then, the trick here is to start any scenario, and kill a buck with your very first shot. Then, fire no more shots in that scenario. This will give you 100% accuracy. Start each other scenario, but do not fire any shots. Your accuracy will remain at 100%. Let each scenario run it's natural course, without firing, for the achievement. If you miss the kill on your first shot, just back out and try again. Hope this helps!
