It is full of enemies with flashlights, a bunch of dead ends and many points where you can easily be surrounded. It is also a very confusing area as there is no map in the game and you have to guess for quite some time in which direction you are running. But don't worry. After reading this walkthrough, you will be able to leave the field quickly and safely.
If you look up, you can see the top of a windmill in the center of the cornfield. Go to her. It is located in an open area, and its bases are bandages and a battery. Look around until you see a barn with light. Go right, keeping close to the fence. Eventually, you will reach large wooden doors with an impromptu ramp next to it. Run along the ramp and jump through the wooden doors.
