Fallen Star Achievement
Retrieve the fallen Sheriff’s star from the ruins of Boulder Creek mineDuring the Protector's chapter, you will clear out enemies in Boulder Creek and speak with one of the nuns as part of the story and she will mention the sheriff is missing. A blue diamond will then show up over the sheriff's wife Naomi. Agree to look for him to start the "Badge of Honor" side-quest, and you'll find his body at Boulder Creek Mine in the first building you see with "HELP" written on the side. Loot his star to unlock the achievement, but be sure to bring the star back to his wife to complete the quest.
