Before moving forth, you can return to the store and sell the non-essential items in your rucksack. There are also new maps in the store, each will reveal the location of items or loot boxes in each area. You can use a nearby vehicle as well to head to your waypoint.
Upon reaching the hunting ground, find the plants conveniently marked in your map then hunt the two boars in the area. Don't forget to find some lootable containers and other scattered items in the area. Also, you may want to use your camera to tag your targets so you can easily track them even if they run away. After completing your objective, open your map then fast travel to the village.
Gather Red Leaf (1), Green Leaf (2) and Blue Leaf (1)
Head outside and approach Dennnis. You'll be in your main menu and will have the option to craft syringes and rucksacks. Nex, you'll have to select some skills to learn. First, learn the Takedown under The Shark skill tree. If you have another skill point available, select another skill of your choice. At this point, I suggest selecting Sprint Slide from the Spider skill tree.
After the tutorial, you have to rescue Lisa. Ride the truck with Dennis until you reach the destination. Once there, new crafting recipes will become available.
