The video starts at flag 5, in the lower terrace of the Garden of Paradise. There are no Templars in Masyaf. Here is an abbreviated table of contents in case you are looking for a specific flag:

Flags 1-6, 0:05
Flags 7-12, 2:25
Flags 13-20, 3:40

For the original setup of how to do this watch Robert de Sable's Early Death.

The gate to Masyaf is closed after you reenter it during the attack in memory block one. When you get far enough away it disappears and is replaced with the original gate. The concept of this is "there is no spoon", and there are other examples of this in the AC games.

While doing this I discovered a few things. First off you can attack Robert off his horse. He is now in a stand up position but still can't be grabbed. Another thing is the assassin hostage the templars killed is still alive (can't believe I never noticed him during my first recording). But back on to Al Mualim. After you make the gate disappear go inside Masyaf. Al Mualim still stands where he was for the previous scene. Move him by gentle pushing or running/jumping at him. Notice how falling doesn't kill him. I have a little fun with placing the two targets together. You are unable to assassinate Al Mualim with the hidden blade, and he doesn't take any damage from weapons which means the only way to kill him is with throwing him into water. Then I kill Robert and continue on with the game to see if anything has changed. During this I discovered the assassin hostage reacted to Altair assassinating Robert, and when I lock onto him it gives combat options on the HUD. Also the two assassins in the leap of faith area are suspicious of Altair. In the next scene Robert is still dead with no one riding his horse. I also included something else in this video. If you move Robert he will fall through the ground at a certain point. Then Altair's health drops to zero and he desynchronizes. If your wondering why it's because when you kill targets by throwing them into water it says "target escaped" on the screen.

The game developers didn't want you to be able to kill targets with water since you had to be right where the target was when he died (in AC1 at least). It's interesting to know that this mechanic is part of a target's programming instead of being a part of the assassination missions.

This video is based entirely upon a glitch reported by Bookeroo on Gamefaqs, Robert Killed In First Memory Block *Spoilers*.
He reported a glitch in memory block one where he fell through a wall, which allowed him to get to Robert de Sables. This video confirms everything he said except I found another way to get to Robert. I start off with an area exploit. Before you reach the room where you activate a trap jump from the structure on the wall and grasp a ledge on the side. You have to jump at a certain angle which allows you to slip past the corner of the wall. It also requires luck since you don't always land in the same place. Once you grasp the ledge move to the side and there are surfaces to move on. To avoid falling off the edges of narrow surfaces use the grab action. If done right you will eventually move up to where the invisible barrier wall ends and can land inside Masyaf. Here are the things said in the gamefaqs topic that have been confirmed in the video.
1. The social status indicator flashed red.
2. You can assassinate Robert de Sable. The animation I performed was low profile done on targets (so I guess this Robert has the same AI as the one in Arsuf, except for fighting you). Too bad I can't ride his horse.
3. After the assassination the sync bar turns red just like in regular assassinations where you are under city alert, but the guards don't try to fight me.
4. After leaving Masyaf and returning the camera angle moves from the leap of faith spot to you. It's kind of like when you restart from that checkpoint, when the assassin complains about his broken leg.
5. After returning Robert isn't there anymore, but most of his men are. The door to the fortress is now open. The assassins on the roof are also still there, except for Al mualim. And the assassins in the leap of faith area aren't there either.
6. Continuing by activating the trap will cause Robert to reappear for the scene.
7. An extra thing I included was proving that the wall where you activate the trap isn't solid. I managed to reach that place early in the game and show what the glitch would have probably looked like.

Assassins are forbidden from using weapons inside their fortress with the exception of the training circle. The third tenet of the creed is to protect the Brotherhood, so Altaïr is not allowed into the fortress when Exposed or Unseen. Unless...

The Turkey Shoot: The goal in these assassinations is to immobilize the target so that you can easily stab him/her with the hidden blade. Of course, the developers never intended such assassinations to be possible, so you have to rely on several exploits in order to pull off these types of assassinations.

Here are video walkthroughs for the assassinations shown in "The Turkey Shoot".

Version 2.0 contains updated blitzes of Tamir, Abu'l, Majd, Jubair, Maria, Robert and Al Mualim.

Blitz assassinations of all the main targets. The concept of this style is to assassinate as quickly as possible, while remaining Anonymous before the kill on certain targets: Tamir, Garnier de Naplouse, Abu'l Nuqoud, Majd Addin, William de Montferrat, Jubair Al Hakim and Sibrand.
