Across the world of The Last of Us Part 1, players can discover many forgotten remnants of the world and the last 20 years that have passed since the outbreak of the Cordyceps Brain Infection. Among the notes left by long-dead scavengers, players with keen eyes can find numerous Firefly pendants left by the many revolutionaries who lost their lives in the fight for a vaccine. As Ellie and Joel get closer to their destination in The Last of Us Part 1, exploring off the beaten path will reward players with these pendants and a trophy for collecting them all.

Chapter four of The Last of Us Part 1 sees the duo arrive in Pittsburgh where they are ambushed by a pack of Hunters looking to raid their gear. To escape the city, the pair must navigate the treacherous city streets, fighting through hordes of enemies and battling all varieties of Infected. This guide will show players where to find all three Firefly pendants in this chapter for the «Look for the Light» trophy.

After the initial ambush, Ellie and Joel will make their way through apartments before emerging onto the street again. After dealing with some Hunters and climbing up over a bus blocking a quarantine zone checkpoint, the pair will find themselves by a large bookstore that acts as a combat area. After clearing out the Hunters, head back outside the front of the store and go into the alleyway to the left of the building; the Kazden Risk Firefly pendant is at the back by a pile of trash.

Much later in the chapter, Ellie and Joel will become separated in a hotel. After reuniting in a cutscene, follow Ellie through some corridors to the exit. Before leaving, enter the women’s bathroom in a hallway on the left.
