Interrogation was used by Assassins as one of the methods of investigation, in order to fully extract information from an individual, in regards to a certain objective. Whilst not completely ethical to other conventional means, an Assassin could use this violent skill in necessary circumstances.
High Middle Ages
Once out of sight from the guards, he would beat his target, and after a few punches, the target would drop to their knees and give Altaïr the knowledge he required. Afterwards, to prevent them from informing anyone of the event, Altaïr would fatally stab them with his Hidden Blade and leave their body on the ground.
Ezio Auditore da Firenze also used interrogation to gain information about his targets, mostly from engineers who were working on war machines designed by Leonardo da Vinci. However, he always used his fists and never killed the individual that he interrogated.
While on the hunt for the Templar keys, the pirate Edward Kenway interrogated subordinates of the key-holders in order to ascertain their location. The former Assassin Shay Cormac interrogated a gang member to find his leader and get revenge on them for bothering Barry and Cassidy Finnegan. Shay's mentor and Edward's son, Haytham, interrogated British soldiers to learn of their plans to overtake New York City, killing them after learning their secrets. Haytham's son, Ratonhnhaké:ton, appalled by his father's ruthlessness, also interrogated Benjamin Church's cart driver to learn of his location. The French Assassin Arno Dorian interrogated Aloys la Touche to learn of his master, the Roi des Thunes', hiding place.
Though it bordered more on torture, Nikolai had Dolinsky tied to a chair whilst he beat him across the face and threatened his family, finally ordering two other Assassins to slit his throat after he disclosed the information about the Staff of Eden and Tunguska.
- If an interrogation target is attacked while one or more thugs are nearby, they will join in the fist fight against Altaïr.
- If an interrogation target is assassinated in front of a guard, they would not react, and behave as if they had just discovered the body.
- When a public speaker was not surrounded by guards, Altaïr could run up and use his Hidden Blade to kill them. Strangely enough, the listeners would calmly walk away afterwards, as if nothing had happened.
- Interrogation missions disappeared in Assassin's Creed II, replaced with ones where Ezio beat an unfaithful husband, though they returned in some form in Assassin's Creed: Brotherhood.
