What if Majd Addin stopped killing people and just walked away? Well... My latest exploit does just that. I introduce to you Back to the Future exploit!

Setup
After killing Majd Addin go to the main gate of Jerusalem. Get the attention of the guards outside by killing the guards inside. Now the guards outside will try to get to you by climbing the beams. Here's a way to get them to temporarily fight you. Hang on the beam by the gate and when a guard comes he will throw rocks at you. Drop down and for a short while he will attack you before going back to the beams. If you manage to counter an attack you will glitch through the gate! Now fast travel out of there and come back.

Back to the Future Exploit
Upon arriving back in Jerusalem the gate will be open (probably because you are not under city alert). When entering you will be told that leaving the city will reinitialize the memory. Go talk to the bureau leader Malik. You will start the mission again as usual. But what has changed? When you get close you will hear the crowd talking as though the scene had just ended. Then you might hear the first victim talk. When you start the scene Majd will start saying what he last says to the first victim, and a few more things in the scene are out of sync. The scene ends with a long pause and Majd killing the first victim. As a result he falls off the stage and walks away. Because you weren't detected there isn't a distance restriction, but you can't follow him without crossing an invisible line that ends the mission. Now there are a few other ways this could end. If you don't hear the first victim speak before the scene you will hear her during the scene, and afterwards Majd will glitch partway into a wall. You are unable to lock onto him or assassinate with the hidden blade but can hit him with a weapon, which can get his attention but might also move him too far into the wall. Another way this could end is by having the second victim talk before the scene. I found that if you get away from the stage you can make more of the after-scene dialogue happen. The farthest I've gotten in the after-scene dialogue is the second victim talking. Now Majd will take a shortcut out of the place by climbing the building. I decided to end the video with an air to assassinate.

The Exploit Explained
Since you fast traveled after the assassination the area was refreshed. And by coming in through the gate you reinitialized the memory. So you start the assassination again, but the game knows you already did the mission, which results in the after-scene stuff happening before and during the scene. It's like the game thinks you are at two different checkpoints at the same time! For Majd Addin it's a tug of war between the scene and after-scene scripting. So the AI gets confused, and Majd is no longer affected by the scripting after the scene.

This video demonstrates a superfast blitz on Maria in memory block six Jerusalem. When you get within the area for the scene you are unable to do any high profile actions. Jump from the fence to the railing which leads you to where you can get in the huddle of the scene. Just go along the railing until you cannot move further because of an invisible wall. To get past the barrier drop down and hang from the side of the railing. Then move further, climb up and drop off the railing past the invisible barrier. You are now in the scene. For the blitz just stand behind Maria and start tapping the button while the scene ends (remember to equip the hidden blade before starting the scene).

Blitzes: For the first blitz the camera view changes in .07 seconds, but Altair is just standing there. The kill animation starts in .14 seconds. For the second blitz the camera view also changes in .07 seconds, but I'm not sure if that's when the kill animation starts (also Altair's health bar appears a frame before the white flash). So I'm not really sure what the correct times are.

This is a collection of previously unpublished comedy bits:

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".

Here are some extremes of hiding in plain sight.

William: After William is done lecturing his men, he goes to his desk to study a map. You can climb down behind William and blend right next to him. If you bump into the table, William will notice you, so you need to be careful as you approach the table. In this video, I line up Altair's shoes with William's shoes to ensure that Altair doesn't bump the table.
