Assassin's Creed 3 - How to do Syncronized Kills in Wolfpack

Audio in spanish (sorry for the english speakers,... it's for you to learn the so cool castilian spanish) In this video I'm showing how you have to do a syncronized kill with your teammates. They key for this is to aim to one target (one who haven't been targeted by your teammates), get into the circle your target is and wait for the others to target their respective targets. Then, when the bar appears, press quickly X (for the Xbox).
