Main Story - The Lay of the Land

Head out to the mission following the marker on the map. Climb up the tower and search everything you can atop this survey point. There are lots of missions and resource materials you can find here. Also, lots of zombie hordes will be found. Prioritize the survivors needing rescue first, then bring them back to the home base, this will make you get Logan as a new playable survivor. This applies to other survivor groups bunkered to smaller areas as well, save them if there are hordes incoming to their areas. Then do the scavenger missions and resource materials missions. You need to bring one resource bundle at a time so you have to back track for the others. If there are Hordes and Infestations, clear them out before they spread too fast.
