Finally, return to the boat to talk to Mowen and you’ll head into the city for supplies before moving on. First you’ll go to pick up something special for Mowen. It’s in a red cargo container, and a relatively safe job there. Clear out a few zombies, climb the ladder on the stacked containers, and jackpot. There’s a mod in here, as well as a decent weapon and Mowen’s package. Follow the radar to a gas station where you can load a truck up with two tanks and get moving. Use the truck to block the entrance to the dock so you’re covered when you unload.
After that you take the boat to the resort for some repairs before heading out. Once you reach the beach, you’ll fetch some steel rods, which is pretty easy by comparison to prior missions. Then Jin goes off on her own for a cutscene. After that you’ll run back to the lab for an emergency.
In the lab, it’s been overrun, of course, and you have to clear out the zombies in the main lab before you can let Yerema out of her cell. There’s a computer where you can release her once the coast is clear. Once you do, you’ll have to find some antidote which is in the fridge. The game now warns you to get whatever else you need, because once you leave the island for the prison, that’s it. Use your fast travel maps to hop around a bit and stock up as much as you can. Once you’re ready, use the radio in the lab to signal that you’re done, then you get a cutscene.
