Fahrenheit features multiple endings and significant story branches based on your choices throughout the game. While this guide focuses on a generally 'good' path, understanding how to unlock others adds replayability.

- Key Dialogue Choices: Certain dialogue options, especially in later chapters, can drastically alter character relationships and the ultimate fate of the world. Pay attention to choices that seem to align with different factions or ideologies.
- Character Survival: Whether certain characters survive to the end can impact which ending you receive. For example, keeping both Carla and Lucas alive is often required for more positive outcomes.
- Mental Health State: The final mental health state of Lucas and Carla can influence their actions in the endgame and the epilogue. A 'broken' character might make different, more desperate choices.
- Relationship Status: The strength of Lucas's relationship with Tiffany, or Carla's with Tyler, can open up unique dialogue or support options in critical moments.
- Evidence Gathering (Carla): The thoroughness of Carla's investigation can lead to different conclusions or paths for the police.
- The Oracle's Influence: Your interactions and choices regarding The Oracle and the other supernatural entities will directly impact the final confrontation and its resolution.
To experience all endings, multiple playthroughs are necessary. Experiment with different choices, especially in the latter half of the game, to see how the narrative shifts. The game encourages exploration of its branching paths.
