The third hour of gameplay in The Last of Us Part 1 typically encompasses a significant portion of Chapter 3: The Outskirts [1]. This chapter introduces players to more complex gameplay mechanics, environmental puzzles, and a wider variety of enemies, moving beyond the tutorial-like nature of the initial stages.br br The chapter begins with Joel, Tess, and Ellie departing from Joel's apartment to escort Ellie to the Capitol Building, located just outside the Boston Quarantine Zone [1]. This journey involves navigating through various urban environments, including abandoned buildings, subway tunnels, and a museum, each presenting unique challenges [1].br br Key Gameplay Elements and Progression:br br Initial Navigation and Stealth Encounters: Players will immediately encounter human enemies, requiring the use of stealth and environmental cover to avoid detection or engage in combat [1]. The game emphasizes staying low and utilizing distractions like bricks and bottles to manage enemy patrols [1]. This section also introduces the use of generators for powering elevators and navigating through tight spaces like crawlspaces and ladders [1].br Introduction of Clickers: A significant development in this hour is the introduction of Clickers, a new and more terrifying type of infected [1]. Clickers are blind but highly sensitive to sound, making stealth crucial for survival [1]. Players learn that shivs are essential for silent Clicker takedowns, though shivs are scarce and break after one or two uses [1]. Headshots are also an option for eliminating them [1].br Resource Management and Upgrades: The third hour also introduces key resource management and upgrade systems. Players will find supplements, which can be used to enhance Joel's abilities such as health, listening distance, or weapon sway [1]. Additionally, workbenches become available, allowing players to upgrade Joel's weapons using scavenged parts [1]. It's noted that fully upgrading all abilities or weapons in a single playthrough is not possible [1].br Environmental Puzzles and Collectibles: The chapter features more intricate environmental puzzles, such as moving objects to create pathways or using the environment to bypass obstacles [1]. Numerous artifacts and Firefly pendants are scattered throughout the levels, encouraging exploration [1]. One notable puzzle involves finding a combination (03-43-78) for a safe in a bookstore, which is obtained from an artifact in a nearby medicine store [1].br Combat Scenarios and Weapon Acquisition: Players will engage in more intense combat scenarios against both human enemies and infected [1]. The revolver is acquired from a dead soldier, expanding Joel's arsenal [1]. The game also introduces situations where Joel must fight alone against multiple infected, including runners and clickers, emphasizing the importance of stealth and strategic engagement [1].
