Assassin's Creed Revelations Part 2 – A Narrow Escape

Once you are in control follow the Ghostly image of Altair up the free run course. Follow this ghost up to the top of Masyaf's Keep. At the balcony ledge you step inside and Ezio collects all his weapons. Go out and up the stairs to take on a few Templars. This is your chance to learn about the combat system.  Run forward and start climbing the building. Pause when you get to the wooden board just above the window. Jump to the left and continue your climb. Go up then to the left, keep an eye on the ghostly Altair.

After you encounter the guard you need to assassinate from the ledge, head on forward and get some more practice with free running. You will encounter another Templar but it is very easy to walk up from behind and kill him. Continue up and interact with the statue. Ezio now dives after the statue.

After you get out of the water kill the guard. Head down the corridor to your left and follow it along. You will reach a chamber with a number of guards and the explanation that you need to drop in and Air Assassinate them. Head to the left and swing onto the beam. Move forward, lock onto your first target and when you are close enough, use the Assassinate option. Now move over to the nearby pillar and run up and get back on the beams. There is a second Templar nearby who may notice you. Lock on and kill him too. Head over to the opposite side of the room, repeat on the sole Templar by you. Now make for the front of the room. Kill that remaining Templar to clear the room.

A cutscene ensues that finishes out the memory.
