Thanks to the following users for their YouTube videos:



-Thanks to Crosby v2 - For all those, who have got some problems with Da Vinci's Tank-Mission:
Instead of doing it the way you're supposed to, there is also a lot cheaper way to get the full sync in this mission. All you have to do is, right when you crossed the final gate, shoot the "cover" in front of the right tank, then immediately go behind the white Desynhcro wall (it's behind you, the direction you came from) and stop right at your 1st warning. Just stay there and keep firing at them. As they are not able to hit you, it shouldn't be a problem to get the 100%

-Thanks to Weezleram - If you change your outfit you will revert back to the previous checkpoint. This is VERY useful for some of the memories, if the memory is long and you are about to lose your full sync condition just pause and change your outfit so you won't have to replay the entire memory. This is highly recommended for the Hell on Wheels memory (if you won't be able to get out of the way of a cannon/tank shot you can simply revert to the last checkpoint instead of starting the entire memory over.

-Another Tip: If you appear to be missing some Sync % still, you need to activate the courtesans and thieves missions by visiting the associated guild. It wont show up at all otherwise. I had this issue with the thieves guild, completely missed them out and was wondering why I was missing 10%

That's it. Basically every mission in the DNA menu that has a Sync % next to it.
