As you progress through Act 2, you'll encounter 'Fear Rooms' – surreal, often disturbing areas that represent the Neighbor's past traumas. These rooms are less about traditional puzzles and more about navigating a psychological landscape. One such room might involve a giant, crying baby, or a school classroom. Your goal in these rooms is usually to reach a specific point or interact with a symbolic object to trigger the next sequence.
The final key for Act 2, often the Purple Key, is usually found after completing a series of these fear-based challenges. It might be located in a high-up area, requiring you to build a stack of boxes or use a trampoline to reach it. Once you have this key, you'll typically use it to unlock a large, imposing door that leads to the end of Act 2, transitioning you into the final act. This section is often the most challenging due to the Neighbor's heightened aggression and the disorienting environment.
