Assassin's Creed for the Sony PS3 got released a week ago. If you are stuck or just do not have the time to figure out how to finish the game, OC Modshop published a complete walkthrough for Assassin's Creed to help you out.

Quote from the guide: "Okay, after learning of the sci-fi twist in this game, just watch the events that unfold and do as you're told until you are put in a hazy looking place. Just run forward and then the tutorial will start. Listen closely and then you will enter a sequence where you learn the controls. Press the head button and look at each group of people around you.
Then walk forward while pressing the "gently push" button to walk through the jar-people. Then press the button that changes your profile (which changes what the buttons on the HUD do). You will notice the low profile actions are acceptable, while the high profile actions will get you into trouble. "
