Steel towers, silent streets, and danger around every corner-Pittsburgh hides more than just clickers. From hidden comics to Firefly pendants, every collectible tells a story of what’s been lost and what’s worth saving.
Once you finally get a working car, you’ll arrive in “Pittsburgh“, the fourth chapter of The Last of Us Part 1. In this chapter, you’ll need to find seventeen artifacts, three Firefly pendants, fifteen optional conversations, four training manuals, and four comics. The collectibles are spread out across four sections: Alone and Forsaken, Hotel Lobby, Financial District, and Escape the City. 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 “Pittsburgh.”
Alone and Forsaken Collectibles
In the chapter “Alone and Forsaken,” players can find several collectibles scattered throughout the Pittsburgh section, including artifacts, Firefly pendants, comics, and training manuals. Carefully search abandoned buildings, wrecked vehicles, and side alleys, as many items are hidden off the main path. Pay close attention to notes and pendants left behind-they reveal extra story details about the city’s survivors. Thorough exploration not only helps complete the collection but also deepens the sense of place and history within this tense part of the game.
The “Alone and Forsaken” section of “Pittsburgh” starts with Joel and Ellie driving their car through PIttsburgh only to be attacked by people in the street. This section ends when you reach the hotel.
