Post-Game Considerations

After completing the main story, you can continue to explore the galaxy and complete any remaining side missions or DLC content (such as Omega or Citadel). However, be aware that the narrative context will have significantly changed.

  • Omega DLC (if owned): A standalone story focusing on Aria T'Loak's reclamation of Omega. Can be played at almost any point after the Citadel Coup, but often feels best after securing most alliances.
  • Citadel DLC (if owned): A light-hearted, character-focused story that serves as a farewell to your squad. Best played just before the final assault on Earth (Priority: Cerberus Headquarters or Priority: Earth Part 2), as it provides a natural narrative break and a chance to reconnect with all your companions.

Remember, Commander, every choice matters. Good luck, and may the galaxy remember your name!
