This should be your first big mission for the Sheriff, and doing it will unlock her second job that requires a lot more investigation.
For now, choose to help find supplies for the survivors. You’ll get a chance to look around the town and get your bearings.
First of all, you’ll need to figure out where all the items you need are. A phonebook should help, there’s one underneath every pay phone in town, and underneath the phones in the corner of the Sheriff’s office.
Interact with the book to complete this tier, and you’ll be given waypoints showing you the way to the next areas you’ll want to explore.
Now you only need to head down to Susie’s Diner. The town itself is full of zombies, so you’ll need to take care while travelling. If you’re going to run, stay away from the marauding hordes of the undead, they’re mostly focused on the bodies they’re eating.
At the Diner, kill the undead waitstaff and pick up three cans of food behind the counter.
The next location is a lot closer. Head up the street to the gun store, and look for the ammo where the metal sheeting has been pulled up. There’s another group of zombies here, so take care of them before grabbing the ammo.
Further up the street is the hardware supply store. Click the door and prepare for a surprise. A giant monster will appear, you only need to stay out of it’s groundslam attack to stay safe. Keep moving – but don’t move too far, you don’t want to back-up into another group of feasting zombies during this fight.
The Jury-Rigged Protector’s area-of-effect attack is much larger than the previous giant zombie you fought, so keep your active dodge ability ready for when it’s about to strike. When you see those white outlines, dodge out.
Next is the pharmacy next door. Interact with the door to find it is locked. You’ll need to find another phonebook for an alternate source of first aid. There’s a phonebook on the street corner’s pay phone north of the pharmacy, you can’t miss it.
Your last stop is the Volunteer Police Department. The zombies there are special, and they’re all armed with axes. Be careful to fight these tough undead one at a time if you can.
Skip the first floor, and use the stairs outside the building to get to the second floor. There you can find one first aid kit in the break room table, one on the wall in the next room, and two with the beds.
Now all you have to do is return to the Sheriff and interact with the storage room doorknob to give up the supplies. Now you can move on to the next mission.
