|Achieve 100% Synchronization in all Sequences.|
Each sequence has a percentage you must fill. This achievement requires you to obtain 100% on every sequence. Each memory counts for the percentage. Some memories are simple and do not have any extra objective that can be missed. There are certain memories that will require you to do something special (an extra objective). This can vary on what is it, and when you start a memory it is detailed for you.

Great, I completed Brotherhood, every sequence on 100% to find out there wasn't an achievement for it, unless you bought the DLC.

nice but only 20? why can't they use their brains and make some of the stupidly easy multiplayer achievements worth less like make one that's worth 30, change it to 20 and make this one 30.. or cut one from 30 in half to 15 so they can at least throw in one more single player achievement to make it 50 for 1k. it's not that hard.. but this achievement deserves more than 20 unless this game is going to be extremely short which i hope it won't be

Getting 100% in Brotherhood wasn't too difficult save for a few pain-in-the-ass missions.
I just hope that they don't include stupid ones like the one for not taking damage during the Leonardo Tank mission, etc. Also that one where you had to go undetected while rescuing what's-her-face was pretty tough too.

I think there's optional objectives to get too in missions, it seems that way from the game play I've seen. With any luck they won't count towards the 100%, but no doubt they will. It doesn't seem too difficult a feat anywho, not like Brotherhood and not for 20G.
That flying machine mission. Dear god I wanted to strangle someone.

@ 10, Not requirements, but you could, however, see the % amount of completion in the stats menu and it says: "% synchronisation: ...". This was in Assassin's Creed II, in Assassin's Creed I the only time referred to synchronisation was at the "health bar" and that too could be completed to 100 %.

Wednesday, November 09, 2011 @ 02:53:39 AM
Ah, the joy. I've gotten AC1 100%, AC2 100%, and AC:B 100% and I did the last one before the achievement was there. I LOVE the series, it's nice, fun, relaxing, and well worth it overall, even without achievements. However, with how people are complaining I wonder, before achievements was no-one else a completionist? Getting all the stars in Super Mario 64 or beating all the data replica's in Kingdom Hearts 2: Final Mix? No, so what's the problem. You should try to enjoy your gaming or not play at all.

getting 100% on Memory 7, on the attack, seems impossible without the crossbow. Does anyone know if you can buy the crossbow later, and replay the mission from the DNA screen?
|Comment #24 by T4S3V|
Friday, November 18, 2011 @ 10:41:19 PM
@23 They are all pretty simple to get 100% on. I never bought the crossbow till after I beat the game and hardly use it as it is not always a one hit kill. I am only struggling on "The Mentor's Keeper". I can't seem to find the citizens but I feel like they are in a really obvious spot.

As the achievement says sequences does that mean just the sequences 1-9 or all
the additional memories, ect.?

Saturday, November 19, 2011 @ 12:07:47 PM
I say the hardest sequence is the one with the mission that you have to keep 40 civilians alive. Its by far the hardest. I keep ending up with 36 - 38. Anyone have any suggestions?

are the people you need to protect... (or at least it was what I did)

Tuesday, November 22, 2011 @ 04:33:48 PM
@ 34 On sequence 7, memory 4 you can lure out one group of guards at a time with diversion bombs and then kill them with lethal bombs, you can easily kill them all without losing any health. You can also put down lethal trip wire bombs and get the guards to chase you through a path of bombs. Either way you'll probably have to go back and get more bombs a couple times but it is extremely effective.

Wednesday, November 30, 2011 @ 11:32:55 AM
I can confirm the achievement unlocks when you 100% synch the main story sequences. It popped for me and I still missed to synch one master assassin mission (damn the town crier), I didn't open some treasure chests and even some buildings weren't restored.
Another tip, sequence 7 memory 4, it was extremely useful to open the menu and craft bombs. I could oneshot packs of guard just throwing lethal bombs at them, then open the menu and craft some more.

Just got this! Only the book achievement left to go now...
The first Masyaf Key mission without being detected...urgh. For some reason, when I came back to it after failing at full synching earlier today, Ezio lost all of his bullets, crossbow bolts, poison darts >__< Those sticky poison bombs did wonders for me on that mission because all I had access to was bombs.
Seriously people, bombs are your friend!
|Comment #44 by Eric508|
Thursday, December 01, 2011 @ 02:37:27 PM
sequence 3 mission 6 is easy if you throw cherry bombs in the middle and wait for all the guards to go to them..then hit them with a powerful poison bomb.

Actually real easy considering they took out all the side missions because they
are seriously lazy, replacing them with these "random events".
Moving crates for some old guy doesn't match up to the assassin contracts!
So little replay value in the game :( and on top of that there's no challenge
for free roam, like the Castello with all the guards - I used to love climbing
Nevertheless should be real easy.

@49 All you do is kill the guards at each little black dot on the mini-map, the same one used to indicate the random events!
Do this and your optional objective should unlock! :)

why is this achievement only 20G? one that requires 100% sync in all missions deserves at least 40-50G if anything more..

I just can't stand the fact that they make you restart the entire DNA sequence if you botch the 100% at any point.
This game isn't perfected and Ezio will still do random things or jump the wrong way and if that fails it on you, you're stuck with another 15-30 minutes of catch up to risk failing again...
They need to get way more forgiving with the ability to retry. I get the approach, but we have real lives as well and spending hours on something tedious is just annoying. It's wake up time developers.
Games should be more fun than chore. If we want to complete a game fully, please make it realistic enough to not sacrifice too much real life time. Collecting things is nice, but it gets to a point where you're just tired of the same hunting shit over and over and spend too many re

You can re-do bits after can't you?
I've only just started the game and got 50% sync in the first mission (the 9/9 templars bit)
If I can't re-do that later on I will just restart now.

|Comment #65 by nhburton|
Monday, January 30, 2012 @ 01:15:55 PM
Honestly I've always thought the 100% sync challenge takes away some of the fun of completing the game. AC2 was so much fun because in each playthrough of the game you could change how you completed each mission. This makes playing the game through multiple times pretty redundant because its the same.
I understand Ubi trying to offer something different but from an enjoyment point-of-view being told what to do definitely detracts from the experience. I really hope they bin the sync challenges for AC3.

@ 20. The flag collecting in Brotherhood wasn't that bad. However the feather and flag collecting from AC1 and 2 killed it for me. I hate collectibles. Thats why I have 98.5% in AC II and 97% in AC 1. I loved how they incorporated in game maps in Brotherhood for the 10 feathers and 100 flags. Hated how in this game after collecting 100 Animus fragments I get nothing but 20 GS,no armor or weapons. uggh. ONTOPIC- These weren't that bad only had to repeat 5 missions,they were a hell of alot easier then Brotherhoods Sync missions. Still have yet to get Principle from Brotherhood ha ha. I HOPE THAT IN AC4 THEY TAKE OUT SYNC COMPLETLY. I loved how in AC 1 and AC 2 I DID the mission how I wanted to, The Sync missions take away the AC experiance for me.
