Escape Dead Island

This achievement is story-related and cannot be missed.

You'll get this fairly early on in the game, during Chapter 5, in Dr. Kimball's home in the staff village. You'll need to pick up the combat flashlight to continue down the stairs to the main floor.

It is worth noting that if you backtrack after you acquire the flashlight and go back up the rope that brought you to Dr. Kimball's house, then you go back down the ladder to the area you came from (where you had the fight with the Spitter and a few other zombies), there is a house you'll need to duck to enter that requires the combat flashlight to see. In this house you'll find a medkit and a collectible. It's easiest to just backtrack to get these before moving on to the bottom floor of Dr. Kimball's house and continuing forward with the story.
