Live by the Creed, Die by the Creed is the final memory of the Jack the Ripper DLC: Evie sneaks into Lambeth Asylum, follows Jack's messages down to the basement and faces him in a boss fight that rewards stealth over brawling.
Part 10 of 10 in Sequence 10: A Monster's Creed
Police surround the asylum. Move through the trees to stay unseen and enter the building, where a room of victims holds another message pointing Evie down into the basement.
Jack shrugs off normal combat and taunts you for trying. Break line of sight, hide and approach from behind to land a stealth takedown. After two of these he uses a fear bomb and calls the inmates to attack, so deal with them as well.
Evie disarms Jack and kills him with his own blade. She finds Jacob alive in a cell, and when Abberline arrives she asks him to make sure no one ever learns the Ripper was an Assassin. He sends the journalists away.
In the undercroft Jack lays out what he wants: the Creed has grown weak, and he will tear the rot out of London so the Assassins can rule through fear. Evie answers that Jacob was like a father to him and that he has betrayed both Jacob and the Creed.
Family Reunion
Family Reunion is the ninth Jack the Ripper memory: you play as Jack inside Lambeth Asylum, killing the staff who remember him as a child patient and burning the records of his stay before Evie arrives.
Autumn of Terror
Autumn of Terror is the second Jack the Ripper memory: Evie Frye arrives at Scotland Yard in October 1888, learns from Inspector Abberline that Jacob is missing, and rides with him to Whitechapel to investigate the first murder scene.
Letters of Intent
Letters of Intent is the fifth Jack the Ripper memory, dated 3 November 1888: Evie gets a lead from Abberline, rescues newspaper owner Arthur Weaversbrook from Rooks near St Paul's, and then frees his kidnapped son from Jack's men at the docks.
The Lady Talks
The Lady Talks is the fourth Jack the Ripper memory, dated 2 November 1888: Evie infiltrates Owers Manor northwest of London to assassinate Lady Olwyn Owers, Jack's lieutenant. The guards are expecting her, so stealth and fear matter here.
