How do I unlock the ending where Arthur helps Sean MacGuire?

In Red Dead Redemption 2, Arthur Morgan’s story has multiple endings, but there is no specific ending where Arthur helps Sean MacGuire directly. Sean MacGuire is a member of the Van der Linde gang, and his fate is tied to the main story progression rather than being influenced by Arthur’s choices. However, Arthur’s actions and honor level can influence the overall outcome of the game, including the fate of other gang members and Arthur himself.\n\nTo understand the endings, it’s important to know that Arthur’s story has four possible conclusions, determined by his honor level and a key decision in the final mission. These endings are not directly tied to Sean MacGuire, as his story arc is resolved earlier in the game. Sean’s fate is sealed during the mission ‘An American Pastoral Scene’ in Chapter 3, where he is killed in an ambush. This event is unavoidable and part of the main storyline.\n\nIf you’re looking to influence Arthur’s overall ending, focus on building his honor level. High honor leads to a more positive outcome for Arthur, while low honor results in a darker conclusion. To increase honor, help strangers in need, donate to the camp, and make morally good decisions during missions. For example, sparing lives and helping NPCs in side quests will boost your honor. Conversely, committing crimes, killing innocents, and being selfish will lower it.\n\nIn the final mission, ‘Red Dead Redemption,’ Arthur must choose between helping John Marston escape or returning to the camp for the money. This decision, combined with your honor level, determines which of the four endings you’ll experience. For the best possible ending, ensure Arthur has high honor and choose to help John. This will result in a more heroic conclusion for Arthur.\n\nWhile you cannot change Sean’s fate, you can ensure Arthur’s story ends on a positive note by focusing on honor and making selfless choices. Pay attention to the camp dynamics and interactions with gang members, as these contribute to the overall narrative. For example, contributing to the camp ledger and participating in gang activities can enhance your experience and provide additional context for the story.\n\nPractical tips for achieving a high honor ending include completing side missions like helping the Downes family, aiding strangers in need, and avoiding unnecessary violence. Additionally, regularly check your honor meter in the player menu to track your progress. If your honor is low, consider donating to the camp or performing good deeds to balance it out.\n\nIn summary, while there is no ending where Arthur directly helps Sean MacGuire, you can influence Arthur’s fate by focusing on honor and making morally sound decisions. Sean’s story is a fixed part of the narrative, but Arthur’s journey offers flexibility based on your choices. By prioritizing high honor and selfless actions, you can ensure Arthur’s story concludes in a meaningful and satisfying way.
