The Heist

The Heist was a virtual representation of one of Shay Cormac's genetic memories stored in the Helix, relived by a research analyst through the Animus.

Description
Shay and the Templars focused on taking down the Assassin-affiliated gangs that plagued New York.

Dialogue
Shay listened in on a conversation between the Colonial Assassins. The Assassins departed. Shay met with Haytham and Weeks. The pair witnessed two gang members stealing a civilian's money. Shay chased after the two gang members. Shay killed the two gang members and stole their clothes, so he and Weeks could use them as a disguise. After cutting down the British flag, Shay robbed the treasury, while Weeks set free the fort's prisoners, causing widespread chaos. The pair then fled the fort to regroup, following which they witnessed the arrival of the army.
 * Achilles: What is our progress on the Precursor matter?
 * Chevalier: We are gathering ships and supplies, but it is difficult without a specific destination.
 * Hope: My men can help. I have enough to spare for a crew as well, Chevalier.
 * Liam: Hope has found a way to... reproduce Master Franklin's experiment. We'll soon uncover the next Precursor site.
 * Achilles: And you are confident you can do this?
 * Hope: I am a keen observer, Mentor. The device will be ready shortly.
 * Achilles: Very good. Keep me apprised.
 * Shay: We've yet to find where Hope is hiding... and most criminals in New York report to her now. I better find the Grand Master...
 * Shay: Things are worse than we feared. The Assassins found a way to make the Precursor box work. They're already preparing an expedition.
 * Haytham: Then we must stop them.
 * Shay: Hope controls hundreds of men. The authorities are doing sod all.
 * Weeks: What if we were to impersonate her men? We could commit a crime so big, they couldn't ignore those damned brigands anymore.
 * Haytham: That sounds like an excellent plan, Jack. Make it so. I will find out where the Assassins are hiding.
 * Shay: Is it just me or did the boss tell us to make trouble?
 * Weeks: Enjoy it while you can, Shay.
 * Weeks: Get them, Shay! We'll need their clothes!
 * Gang member 1: I think we're being followed!
 * Gang member 2: You're right! Let's move!
 * Gang member 1: Come on! I'm too young to die! Hurry, you fool! Or we're both dead men!
 * Weeks: Don't we make a disgraceful pair of crooks?
 * Shay: No, I make this look good. So what's the target?
 * Weeks: The military pay. We'll have to hurry. A regiment is already on its way to the fort where the coins are kept.
 * Shay: Great... And I suppose you have a plan?
 * Weeks: The fort holds many prisoners... Get in and hoist the gang's colors. When you do, I'll free them.
 * Shay: You're going to free a bunch of criminals working with the Assassins?
 * Weeks: Well, we have to turn the army against them, don't we? Remember: You raise the flag and I'll raise hell!
 * Captain: What on earth happened here?
 * Guard 1: The prisoners got loose!
 * Guard 2: They had help from outside.
 * Guard 1: There were just too many of them!
 * Captain: Well then, we're going to have to fix that, aren't we? It's about time we took those criminals down.
 * Shay: It worked, Jack!
 * Weeks: With a little luck, the army will crush those damned brigands.
 * Shay: I make my own luck.

Outcome
Shay and Weeks' heist turned the gangs into a target of the British Army.
