After Joel and Ellie barely survive the flooded tunnel, you arrive in “The Firefly Lab.” In the tenth chapter of The Last of Us Part 1, you’ll need to find four artifacts and one Firefly pendant. There is only one section, The Hospital, in this chapter. Read on to find out where all of the collectibles can be found in “The Firefly Lab.”
