The Hidden Blade Assassin's Creed in Depth

The goal is to empty the Sistine Chapel without being detected. You can use a similar process to wield the Papal Staff as a weapon to kill others; this is shown at the end.

If you haven't seen it already, I recommend first watching and reading this article on the "Non-story Rodrigo Borgia Assassination," which has highly relevant information:

The goal of this mission is to kill every guard in the Doge's Palace and Carlo Grimaldi without being seen at all. That means no yellow bars over your opponents.

Most of my videos start at the checkpoint immediately before the assassination mission. This missions starts earlier - at the checkpoint when you land on the roof.

Altaïr returns to Acre in Assassin's Creed II with some slightly different skills. Gone are nine of the ways to wield the hidden blade: low profile, high profile, running, prone, hidden blade counter and taunting penalty. However, he has acquired some new skills. Namely those that he passed along to Ezio through the Codex:

Ghost
The goal is to kill every opponent you that can reach in the "Having a Blast" (Marco Barbarigo) mission without being seen. That means no yellow bars whatsoever. To keep it challenging, I don't use anything other than the hidden blade. This mission is basically the same as the Silent Crash of Carnivale, but on steroids:

Here are some notes:

Anonymous Blitz
An anonymous blitz was previously discussed in Part 1 of this variety pack:

Blitz Assassination

Silent Night at Emilio's Palazzo
The goal is to kill every opponent in Emilio's Palazzo without being detected. Just for fun, I also stay entirely unseen in this mission. That means no yellow alert bars over the opponents. Also, no smoke bombs and a minimal throwing knives, just to keep it challenging.

You may need to get the first patch for AC2, which was released December 2009.

Silent Crash of Carnivale
The goal is to kill every opponent you that can reach in the "Having a Blast" (Marco Barbarigo) mission without being detected. There are lots of ways to accomplish this task - this video shows just one way. This video is not optimal, but it demonstrates some of the techniques that can be used.

Winning the Impossible Fight

Altair's Chronicles | 1190 A.D
Altair, a young but experienced assassin returns home to his city from some work. He finds it under attack by Templars. In order to stop the attack, he fights back using his skills and in doing so kills a low-ranking officer of the Templar army. Al Mualim, his master, gives him the task of finding a very important object named the Chalice. It is able to unite all nations in favor of a single master, and must not fall into the hands of the enemy: thus it must be destroyed.

Throughout his investigation and adventures, Altair discovers that the Chalice is not an object, indeed it is a woman who he has an interest in: Adha. The Templars capture her, and put her on a ship. Altair fights his way to the ship and kills the Templar leader, Basilisk. However, Adha turns out to be on a different ship, and Altair vows to find her, no matter what it takes.

The first time Altair has seen the ferocity of the Templars, and the reason for having a Personal Vendetta against them in Assassin's Creed
