The next cutscene starts off with a few new people from Terra Save running through the forest while Neil distracts the zombies before they run into one of the wooden houses in the area. After a bit of tension, Claire and Moira show up.
Search for helicopter parts
It would be a good idea to go to the main double door and check what is needed for the helicopter. It's also good to have a map. Once you talk to the mechanic, go back in and start searching for the parts marked on the map. A few parts maybe easy to find but later on, a person carrying a chainsaw will come and help get through some doors that need to be struck down with the machine. Make sure to be careful of two things: zombies and supplies. Conserve ammo as best as you can and give herbs and the tourniquet to Moira as you search for parts like petrol for example. This requires going back and forth a few times.
Chainsaw battle gone wrong
The words of the Overseer from the previous episode (that everyone has been injected with a mysterious virus, and should you give in to fear, you'll turn into a monster) are proven true when the man with the chainsaw undergoes his transformation. You have two options here: either fight him until he's subdued, or if this is too much to handle, keep fighting until Neil drops the ladder and calls Claire and Moira over to escape. To be safe, follow him up the ladder and escape the village to someplace else. Be thankful that Barry and Natalia are not too far behind to finish off the chainsaw zombie if Claire and Moira aren't able to, as Barry currently has more powerful weapons at his disposal.
Calm before the darkness
You'll get a break from the zombies for the moment. Follow and talk to Neil, your boss, until you reach the outside at night. Go up another ladder while Neil distracts the zombies on the ground with a gun. The next part may involve a brightness adjustment as you have to walk all the way to the warehouse building, but watch out for those nasty dogs along the way. Depending on the difficulty, it will take about three to five shots or more to take down one dog. Regardless, continue on into the next warehouse building to keep Claire and Moira from being exposed out in the open.
Going through the medical warehouse
It might be easy to breeze through once you're inside, but you'll end up stuck at a dead end, especially if you're playing by yourself. Once you go up and down while clearing out all the zombies, there's a point where you have to run past the gate once you hit the switch, so practice until you get the timing right. The solution is to put the box in the middle of the steel door that has a timer on it so that Claire and Moira can get past it. This may take a lot of tries but you'll get the hang of it. Once that's successful, continue clearing zombies as you reach the door.
