The Hidden Blade Assassin's Creed in Depth

Assassins Creed Unity Sequence 9 memory 3 Hoarders Marie Lévesque

I was going for a variety pack, but things were taking too long. I hope you find this interesting.

Stealth Infiltration of Parais Luxembourg

If you're fast enough the guards can be dealt with efficiently on the way to the target. From the last checkpoint start with treading the wire leading to the building and take out the rooftop gunman while his back is turned. The next two gunmen up ahead start out close enough for a double kill if you didn't lose any time.

Climb up higher, head right and get in through the open window. Go into the small room and quickly kill the guard posted outside. As you move on, two other guards patrol the hallways. Move fast enough and you usually can get them both at a window, although sometimes the game randomizes their locations.

Kill the brute from a corner and berserk the gunman on the far side of the target's room. The target will flee from the conflict. You can beat Marie to her waypoint using the stairs. Just watch out for the brute patrolling in and out of the room and any other guards patrolling around that area.

Now when Marie runs in there you can get a kill without being seen, especially by the guards who are still following her but from a distance due to her running. The way you came has been cleared of guards, so that could make a good escape route, although I haven't tested it.

Assassins Creed Unity Sequence 13 Memory 6 a Crown of Thorns.

The last memory of the sequence and assassination of Captaine Rose.

Stealth

Before the fight with Captaine Rose, it's a challenge just to get to him without being seen.

Using just the hidden blade it's not that hard to make your way through the area. Also took the opportunity to achieve the double assassinations challenge.

When you start down the large flight of stairs, wait for the two guards to pass by and quickly assassinate them. Then kill the raider captain from the safety of a cover. This will cause some nearby guards to flee, making your stealth path easier.

Continuing along the route, corner kill the stationary guard. I've gotten see before by the patrolling guard during this kill, but with the timing in the video I haven't.

Now wait till the patrolling guard can't see you and hang off the edge. By this time some guards will notice the bodies of your first kill. Shimmy your way across and kill the patrolling guard, then the two posted guards. You will complete the double assassinations challenge.

When you reach the next two guards, keep an eye out to your right for guards. Kill them when the coast is clear. You won't have to worry about enemies for the rest of this as long as you keep to the roofs.

Early Death

Now that you've reached the target, time to pre-kill him. Getting close to the area starts the scene, so lure him with a firecracker from a safe distance away. Other guards will also arrive, which can be dealt with using poison bombs.

Now sneak up on the target and... he can't be assassinated or knocked out. Immune to poison bombs and berserk darts. Combine that with lots of health and you're looking at a high level boss.

Now here's the thing: If you kill him then it actually causes the scene to start. Not sure why, maybe killing him is supposed to start the next checkpoint regardless of what part you are in the memory.

Anyway, he respawns after the cutscene, so the pre-assassination is just for fun.

In this video I show a few ways of killing Lafreniére that I though were pretty cool/interesting. This assassination takes place during sequence 5 in memory 3.

Puppetmaster

In this part I let the graveyard caretakers and their friends(green NPC eagle vision, who will help you if you kill the bodyguards before Lafreniére arrives, do most of the work for me. I throw a cherry bomb at a certain spot which will attract a couple of guards, the allies and Lafreniére . They will start fighting and shooting at each other and one of the allies takes out the target for me and I wait until the rest of the guards are distracted by the remaining allies who have heard the gunshots and have gone up from underground to investigate.
Then all I have to do is silently finish Lafreniére off for a completely unseen kill.
I dubbed it puppetmaster because I am sort of pulling all the strings from the shadows and didn't know what else to call it

Blitz
This one is pretty straightforward.
I jump in the haystack closest to the target and before the wait timer is full I quickly jump out in the right direction so I can instantly drop a smoke and run to the target. The actual time it takes from spawning to killing Lafreniére is around 6 seconds, maybe even very slightly below 6 seconds.

I ended up changing things, scrapping my original plan because the route slembroccoli wrote out is much more efficient and it turned out my planned route had a serious flaw. The main run in the video is exactly what slembroccoli described here: http://www.thehiddenblade.com/looking-future-again-thread-text-walls#com.... It is indeed the best way of doing this mission in a minimalist fashion, which I think is pretty sad honestly. Regardless, awesome work, slembroccoli. I included my original infiltration route as well, after the main run, and I talk about its flaw in the video's annotations.

Happy holidays everyone.
