The Hidden Blade Assassin's Creed in Depth

Anonymous Blitz
Without a lock, Ezio will throw a knife in the last direction of travel. Look over Ezio's head to fine tune your aim.

Viewpoint Assassinations
The target starts the mission near the viewpoint, but then proceeds toward the other end of the court - walking back and forth along an L-shaped path that is too far from the viewpoint to do much. However, if you act quickly, you can reach the top of the nearby viewpoint and perform some fun assassinations on the banker while he is within range.

Parachute Air Assassination
I wait until the Banker walks past the corner of the column base before jumping to ensure that I can lock on for the air assassination. If you jump too early, you will overshoot and you won't be able to lock onto the target....

Parachute Drop Stunt
If you overshoot, you can still drop down for an assassination if you time it right.

Viewpoint Stunt
Jump from the viewpoint, land on the rail, and air assassinate. I had lost a few bars of health from an earlier stumble (not shown in the video). I nearly desync on this stunt, which gave an unexpectedly nice slomo kill animation. I may intentionally use this trick in the future.

Eagle Strike
I jump directly away from the side of the viewpoint to precisely control the aim. Ezio dies if he misses catching the ledge.

Stunt
Unlike the previous assassinations from the viewpoint, you can take your time in setting up this stunt.

Long range spear
Unlike other weapons, long weapons are never sheathed, so you can pick them up even if you quietly kill the guard that holds it. I use this as an opporunity to kill the target at a distance. Looks like it hurt, too. Spears don't have any effect beyond a certain distance, which I think is limited to 20 meters. Ezio will step forward as he throws the spear, so I initiate this throw at 21 meters. By the time he releases the spear, the distance is at 20 meters.
