Visit to the Pub
Obtained from: Dwight Turner
Reward: 3000 Exp, Nail Hammer
Obtain the warehouse key from the mechanic
Dwight stands in front of the warehouse door (1) #1. Unfortunately it is closed. A key belongs to a mechanic who is dead but now walks amongst undead. You can find him in the bar. To get there go to the back of the building (2) where you'll find few boxes. Move them that way, so you can jump up over them #2.
Break the bar's door and get inside. You'll face two Walkers and a Thug #1. There is not much room there so be careful. Once the mechanic is dead, take the key #2 and bring them to Dwight (1). You'll get a reward plus you can take from the warehouse whatever you want.
A Matter of Honor
Obtained from: Makimbah
Difficulty level: Medium
Reward: 3000 Exp, Brutal Machete
Rescue Makimbah's bride from the rival village
Makimbah sits between huts next to the car (1) #1. He will tell you that his fiancé has been kidnapped by hostile tribe and he is to big coward to get her back. Right next to the man you'll find a map for Fast Travel option - use it and move to The River Village. Mahina is kept in one of huts (2). As the door is closed you have to find another way to get inside. Use a wooden catwalk #2 and jump onto the roof.
Now get to the roof of the hut where Mahina is kept and jump inside through the hole #1. You'll find Mahimbah's wife there #2. You'll learn from her that her husband was beating her and that's why she escaped. She will ask you to tell her husband that she is dead or turned into a zombie.
Unfortunately words are not enough so you need some proof. Mahina recently threw out her necklace which she got from her husband. Look for it near Gaia Falls (3) #1. You can't drive shorter way with a car because and exit from the village is blocked. You must walk there or choose a longer way by a car. You can also use Fast Travel to get to the village on the north and then use a car to get to the falls. The necklace can be found in a bus - you have to take a decent running start and jump on the bus from the opposite side #2.
The necklace is in a small bag #1. Take it and return to the village. Tell Makimbah #2 that his wife is dead - he will believe you.
