I have been playing Assassins Creed Brotherhood lately.:) I just beat sequence three, and I have acquired seven assassin recruits that are on average level 7.:) I use them a lot, for instance i sometimes run around Rome and get a lot of gaurds chasing me then I call them and about 10 seconds later all the guards are gone.:P
As you can tell that is a GS image not mine.
PS: After you beat the campaign can you continue roaming around like in ACII?
Thanks for reading, have a great day.:D
