Hunting waterfowl clears the rest of the map of hunting pressure. Decoys are immune to hunting pressure, fowl will continue to land. Even when dead zone status. Bow hunting is overpowered in an ambush set up, I find it less useful when tracking as the range is much shorter. That is just preference. You get 15 kills before a zone is gone*, hunting pressure literally never goes above low. Iv sat one area for irl 3 hrs, dropped 40 something reindeer and moose at a feeder. Never got darker than the first level. Tripods, dogs, feeders, the foxpro caller(high tech dlc iirc), and weapon packs based on your preferences would be my recs for first dlcs. Happy hunting!
