Assassin's Creed Brotherhood Brutes and Brutality (Full Synch)
Full Synchronization guide to the assassination contract: Brutes and Brutality. There is a squad of Brutes that need killing, and to get Full Synch, you need to do this in under 15 seconds. Seriously, you are not thinking of going in there with your sword waving, are you? Use your Recruits' Arrow Storm attack, and mop up any leftovers. By now, you should have recruited enough Recruits for 3 signals worth.
