Assassin's Creed: Brotherhood 100% Synch Memory Sequence video guide

SEQUENCE 3: The Fighter, The Lover and the Thief

100% Reward: Killing Spree

Enables you to execute enemies instantly during fights.


Memory 1

Double Agent
100% Requirement: Don’t not be detected while reducing Notoriety. Remain undetected until rejoining La Volpe at the Thieves Guild.


Memory 2

Between a Rock and a Hard Place
100% Requirement: Kill only the Borgia Captain

This memory will have you wanting to kill more than just the Captain.  The Captain can be taken rather quickly from the start of the memory, but once he is down, you will need to ignite the Borgia tower.  Trying to climb up it with a bunch of enemies tossing rocks and arrows at you can be tough.  Run around the tower to lose them and start your way up once they are out of sight.  Remember, no matter how much you want to drop and just start slaughtering them all, don’t.  Keep heading up and torch the tower for the 100%.


Memory 3

High-Stakes Negotiation
100% Requirement: Do not swim

To quote Donny from Gone in 60 Seconds, “I can't swim, I know I can't. So you know what I do? I stay my black ass out the pool.” And that’s all you need to do for this 100% synch.  No matter how much you want to hop in the water, don’t do it. The only tricky part here is to not fall in the water when going over to the boat or back from it—like I did. Repeatedly.


Memory 4

Collective Intelligence
100% Requirement: None

SEQUENCE 4: Den of Thieves

100% Reward: Sisterhood

Turn all your Assassin recruits female


Memory 1

Castello Crasher
100% Requirement: Do not be detected


Memory 2

Femme Fatale
100% Requirement: Do not lose more than 10 health squares

These “do not lose more than X health squares” syncs are the best.  Simply carry a load of medicine with you and whenever you get a little close to the requirement, pop one and keep your health up.


Memory 3

The Burdens We Carry
100% Requirement: Do not be detected


Memory 4

Guardian of Forli
100% Requirement: Achieve a kill streak of at least 5 guards

When Catherine and you take off on the horses, wait until you reach the far side of the bridge and you dismount.  When you do, a few guards will rush over and in time, a whole slew more will appear.  Stay on the far side of the bridge, for if you go to far from where you began, you will desync. Keep blocking until there are enough enemies around that you can start a streak with and then go nuts.


Memory 5

Man of the People
100% Requirement: Do not lose more than 5 health squares

Another health square memory where you can keep popping medicines to keep your health above 5 squares.  Just make sure you have some medicine on you before starting.


Memory 6

Serial Offender
100% Requirement: Kill your target using the Assassin Recruits

Cake. Summon your henchmen for the kill while you sit back and have a beverage or a sandwich or whatever it is you do.


Memory 7

Human Cargo
100% Requirement: Kill your target using the Assassin Recruits

Again, just as easy as the previous memory. For this one use your recruits while you finish your beverage or sandwich or whatever you decided to do on the previous memory.


Memory 8

An Unexpected Visitor
100% Requirement: None


Memory 9

The Plan
100% Requirement: None

    Does using any of those cheats prevent the earning of achievements?
  • 04whim - January 11, 2011 9:08 p.m.
