The first part is simple. Take out your sword, as you will be fighting all your 
previous assassination targets. They are fairly easy to kill. Only one counter is 
required to kill each of them. For the second part, as soon as Al Mualim releases you,
use your Eagle Vision. The real Al Mualim is the one in yellow. Focus your attacks on 
him. In the third part, Al Mualim takes away your synchronization bar and radar, 
allowing him to kill you in one hit. Take out your throwing knives. Look for the Piece
of Eden in his hand. Once you see him, throw a knife at him. Then, just counterattack/
grab break him. Keep repeating this until he says, "Damn you Altair!" Finish him off 
with your hidden blade or keep attacking him with your sword until he is dead.
