just real quick what am i suppose to do at the swamp???????

HELP im at the swamp (chapter 2) and so far all i have done is wonder around aimlessly and get killed over and over again. i have no idea what the heck im suppose to do here, like what the goal even is or anything.

like in chapter one the goal was clear, its just to do all the stuff wolfman tells you than you find the doc and get the key, but here i dont even know what the hell im doing. also its freaking huge and i have no idea how to navigate this god forsaken place.
