Assassin's Creed Brotherhood Leader Of The Pack (Full Synchro)
Full Synchronization guide to the Lair of Romulus map called "Leader Of The Pack". You must not lose more than 10 health squares for this one to fully synch. Expect ALOT of Romulus Followers in this one, plus a couple of navigational challenges. There will be 3 separate pursuit sequences in which Followers appears from the sides to ambush you. I highly advise that you avoid combat with them, and focus on chasing down the fleeing Follower. This will reduce the chance of you breaking the Full Synch requirement.
