How to unlock the Betrayal in blood achievement in GreedFall - Definitive Guide
To obtain this achievement you will need to have progressed through some of the main story missions without ever doing Kurt's companion quests. This is so Kurt's friendship level with you is set to Suspicious. When you return to Constantin to inform him that the previous settlers on the island were part of the Merchant Congregation (The quest is called The Prince's Secret) Kurt and some guards will storm into the throne room and inform you that a Coup has started. If your relationship with Kurt is Friendly then he will take your side and help you stop it which will earn you
But will prevent this achievement from being obtainable.
If your relationship with Kurt is 'Suspicious' or "Nice" then you will have to fight him in Constantin's throne room and choose to kill him. This will unlock Betrayal in blood, but not until you pick a city. I suggest saving your game as soon as you can as you will next have to pick between two cities to save from the Coup. You can only save one, so do one, load your save, then do the other to obtain the following two achievements:
This achievement is unlocked by having Kurt betray you during the Coup D'etat, and cannot be obtained along with "Missed coup" without the use of save manipulation. To unlock both of these achievements with the same character you will need to play the game until you have completed Kurt's first companion quest, 'Missing in Action' but don't go so far as to have completed 'The Prince's Secret', then make a backup save. Now, with only Kurt's first companion quest completed, finish 'The Prince's Secret' to trigger the Coup D'etat and during it, Kurt will betray you and you will ultimately unlock this achievement after finishing the quest.
Note that you need to continue with this playthrough so that you can unlock 2 further achievements tied to this path, "In the name of the Enlightened" & "A preserved Alliance". See their descriptions for more details.
After having unlocked all 3 of those achievements, reload your backup save and then proceed to complete Kurt's second companion quest, 'Amongst the Ghosts' before then going on to complete 'The Prince's Secret', which will ensure he stays loyal and allow you to unlock "Missed coup" after completing the Coup D'etat.
It is important to do it in this order, since you will need Kurt loyal for the rest of the game to be able to finish all of the companion quests and unlock the various endings.
