The Quarry is the latest narrative horror game from Supermassive Games. This one features a set of camp counselors who get stuck at camp one extra night, which results in an ensuing bloodbath. The villains of the game are the Hacketts, the family that owns the camp and the quarry it takes place in. It’s possible to kill every Hackett in a single playthrough, netting yourself an achievement/trophy to do so. This guide tells you every opportunity you have to kill each member of the family. GameSpot’s best ending guide will also result in all of the Hackett’s dying. It’s also important to note that you need to keep as many counselors alive as possible in order to get these opportunities. Spoilers ahead.
There are seven members of the Hackett family, with an eight villain that isn’t necessary for the achievement, but does unlock their own achievement/trophy. Kaylee is the first member of the family to die and will always be killed by Laura and found floating in a pool in Chapter 5. You don’t have to do anything to trigger this, it always happens.
Travis will die in either Chapter 9 or Chapter 10, depending on what decisions you make earlier in the game. These decisions come as Laura in Chapter 7. The first option is to take the gun from Travis and shoot him once in the jail. This will cause him to show up in Chapter 9 and kill Laura, then get killed by Ryan. The second option is to grab the syringe from the second floor office as Laura in the police station. After that, stash it in the wall and use it to subdue Travis. This will result in him helping Laura and Ryan in Chapter 9.
