Assassin's Creed/Memory Block One

Tutorial
Watch the little twist at the start of the game and then move on to the tutorial. Listen and follow what the semi-annoying voice tells you to do. First push the head button and look at the each group of people near you. Next walk very slowly while holding the "gently push" button to go through the jar head people. Press the button that changes your profile from low to high. Notice that your actions change as well.

Now comes the stuff that is slightly more fun. High profile it up, grab the dude, and through him into the spot. Beat the guy to the spot by holding in the high profile button and the sprint button. Now you can go kill a guard. After that a guy will come out and become suspicious after seeing the dead guy. Do something like jumping to make him informed. Run up the ladder and jump into the roof garden. Wait until the guard goes away to come out. To walk by the guards just go into blend and walk into the target.

You then get a new ability called eagle vision which can be used to see if a guy is a villian, ally, etc. The voice then tells you of the three rules of the creed: 1. Don't kill innocent people. 2. Be discreet. 3.Don't jeopardize the clan.

Getting Started
When the level starts watch the cutsceneand hit any button when there is a glitch.(A glitch is when the screen kind of messes up and if you hit a button, then it gives you a cool new view on the action.) Go forward hold the high profile and sprint buttons down at the same time to run across the beams. Climb up the ladder and assassinate the guard to trigger the next cutscene.

Go down to meet Jean Robert. After he talks to you, hit him with the assassination button. He will send you flying through the air. Time to run away. Climb up the wall just like you would a ladder. Eventually it will fast forward in memory.

Masyaf
Talk to the friend for a second before running up the hill. You don't have to blend or anything here because these guys are your friends. You'll run into another guy that knows you, but this guy really isn't your friend. Go into the fort, then into the building, and up the stairs to talk to Al Mualim.
 * Objective: Talk to Al Mualim
