How do I unlock the “revenge against Micah” ending?

To unlock the "revenge against Micah" ending in Red Dead Redemption 2, you must make specific choices throughout the game that influence Arthur Morgan''s honor and the story''s outcome. This ending is tied to the high honor path, where Arthur seeks redemption and prioritizes helping others over selfish gains. The final confrontation with Micah Bell occurs in the Epilogue, but your actions as Arthur in the main story directly impact whether this ending is available.\n\nFirst, you must maintain high honor throughout the game. Honor is a core mechanic in RDR2, influenced by your decisions and interactions with NPCs. To increase honor, help strangers in need, donate to camp funds, and make morally upright choices during missions. For example, sparing lives during robberies or helping the Downes family early in the game will boost your honor. Avoid actions like killing innocents, robbing civilians, or antagonizing NPCs, as these lower your honor.\n\nDuring Chapter 6, Arthur''s health deteriorates due to his illness, and the story branches based on your honor level. If your honor is high, Arthur will prioritize helping John Marston escape and securing his family''s future. This sets the stage for the Epilogue, where John takes center stage. After completing the main story, you will play as John in the Epilogue, which spans several in-game years and leads to the final showdown with Micah.\n\nIn the Epilogue, John builds a new life with his family at Beecher''s Hope, a ranch near Blackwater. After completing the ranch-building missions and reconnecting with old allies like Sadie Adler and Charles Smith, you will receive a mission called "American Venom." This mission is the culmination of the revenge arc against Micah. To trigger it, ensure you have completed all required Epilogue missions, including "The Wheel" and "A New Jerusalem."\n\nDuring "American Venom," John, Sadie, and Charles track Micah to his hideout on Mount Hagen. The mission involves a tense shootout and a climactic confrontation. If you followed the high honor path as Arthur, this ending will feel like a fitting conclusion to the story, as John avenges Arthur''s betrayal and death. However, if your honor was low, the ending may feel less satisfying, as Arthur''s actions would have been more self-serving.\n\nTo ensure you unlock this ending, focus on maintaining high honor from the start. Pay attention to dialogue choices, mission outcomes, and random encounters. For example, during the mission "A Short Walk in a Pretty Town," choose to spare the lives of enemies when possible. Additionally, complete side activities like helping strangers or donating to the camp to boost your honor. These small actions add up and significantly impact the story''s direction.\n\nPractical tips for maintaining high honor include avoiding unnecessary violence, greeting NPCs politely, and participating in camp activities. If your honor drops, you can restore it by fishing and releasing the fish, helping strangers, or donating to the camp. By following these steps, you will unlock the "revenge against Micah" ending and experience one of the most emotionally impactful conclusions in Red Dead Redemption 2.
