Find where all of the artifacts and optional conversations are located in the Back in a Flash, Mallrats, So Close, Fun and Games, The Enemy of My Enemy, and Escape from Liberty Gardens sections of the Left Behind DLC of The Last of Us Part 1
In “Left Behind,” the sole major expansion for The Last of Us Part 1, you’ll need to find twelve artifacts and thirteen optional conversations. The collectibles are spread out across six sections: Back in a Flash, Mallrats, So Close, Fun and Games, The Enemy of My Enemy, and Escape from Liberty Gardens. The game does not indicate to you when you’re moving onto a new section, but you can select and begin playing any section from the Chapters option on the main menu.
Read on to find out when each section begins and ends, and where all of the collectibles can be found in “Left Behind.”Back in a Flash Collectibles
The “Back in a Flash” section begins after a few cutscenes where you meet Ellie’s late best friend, Riley. You gain control of Ellie after the events of the main game’s “The University” chapter concludes, but before the “Lakeside Resort” chapter begins. This section ends after you exit the nail salon and hop over the stair’s railing.Combination Note Artifact Location
Once you crawl through the entrance of Weston’s Pharmacy, go behind the counter and immediately turn left to find the Combination Note on the floor.Pharmacist’s Key Artifact Location

Enter the store and head to the back left corner of the store to find a deceased clicker in a lab coat. Interact with it to receive the Pharmacist’s Key.Pharmacist’s Note Artifact Location
After you interact with the deceased pharmacist, the body will slightly fall over, dropping the Pharmacist’s Note onto the floor in the process.Salon Note Artifact Location

The “Mallrats” section starts after a trip back in time to Ellie and Riley’s adventure, and ends after you turn on the mall’s power and follow Riley to set of double doors.Wanted Poster Artifact Location
