I just finished both Hunters 2 games. And I thought that Australia was a little more challenging then America. The grass and tall tress were horrible when it cam to following a scent with the dog or when shooting birds as they are flying from a certain location. I had so much trouble with the Trailing Quail & Hunting Woodcock hunt missions. Other than that nice guide & an easy 400
Also to reach max level. You can replay A Land Of Boar under Marlborough. You will get roughly 4000 points for killing all boars, plus stealth. But this method requires patience. Just wanted to throw this out there.
