The Hidden Blade Assassin's Creed in Depth

Anonymous Blitz
If you don't enter l'Arsenale, you will stay Anonymous and the targets won't move past their first waypoint. This is the perfect opportunity to kill them with throwing knives. They will be too far away to lock onto, so you'll have to aim "manually." Throwing knives travel in the direction of your last horizontal movement. Walk in the direction you would like to aim, and look over Ezio's head to fine tune your aim.
