Converse with fellow players
To unlock the True Ending of Epsiode 6, you need to have completed 3 different Story Quests throughout all the 6 Episodes, one of them requiring an S Rank.
These quests are:
• EPISODE 3 - CHAPTER 4: Plotting the Ultimate Defense. (The fight against Dark Falz Apprentice in Mining Base: Ending)
• EPISODE 4 - CHAPTER 8: Avatar of Annihilation. (The final fight against Deus Hyunas)
• EPISODE 6 - CHAPTER 8: The Hope You Bring. (The quest where you enter the corrupted Mothership and defeat Shiva, you need an S Rank in this quest)
It doesn't matter if you complete said quests on Normal or Hardcore, as long as you meet the requirements, a new option will be available in the last Story Quests to fight the Primordial Darkness: Gomoru and Sodam.
Also after you complete the last quest, remember to check the Story Quest section again to watch the epilogue conversations.
