The Hidden Blade Assassin's Creed in Depth

Mister Walpole, I presume?

During this memory you are introduced to the main Templars, as well as obtaining a pistol and hidden blades. Time for some exploits.

First off you can remove Edward from the scene with Woodes Rogers and Julien du Casse by being in a climbing position. There is a tree that leads to a railing. Walk up it and wiggle as close as you can off the edge. In the rare event you get close enough you can grasp on to it. Then very carefully move along it until you get the scene to start. There's something else you need to know. If you are in a climbing position where your hands are close together it won't remove you from the scene. You don't see it in the video, but I actually move back to the right when the scene is starting. What follows is an introduction to an invisible Edward and a floating pistol.

Early Deaths

Not bad you can kill the main Templars in the same memory of their acquaintance. The opportunity is right after Woodes, Julien, and you are sworn into the Templar order. By tapping the assassinate button in high profile during the end of the scene you get Woodes and Julien in a double assassination (in low profile you just get Woodes). The strange thing is for Edward the killing animation gets cancelled, giving the illusion they just die suddenly, although dying people don't generally just throw themselves onto a table/the ground. When the time comes for one of them to speak no dialogue is audible for the rest of the conversation. The kill/kiils also cause a glitch with the following scene not starting, preventing you form progressing any further in the game.

You can also get Torres this way by moving the left analog stick to the upper left while tapping the assassinate button on high profile. As for the last guy, El Tiburon, he's either out of reach or invincible to assassinations.
