I heard from some posts that you get repressed memories of Ezio then I heard you get NO rewards. Which is it?!
Also, can I do the Borgia tower missions in the area open to me at any time?! Are those considered "side missions" or will the story take me through the burning of each towers?!
Many people don't consider uncovering backstory a "reward", and usually refer to Trophies or an in game reward as the only rewards. You'll unlock repressed memories, the final one being unlocked at 75% overall Sync.
You get Ezio's repressed memories when your total synchronization reach 15,30,45,60 and 75% and you get some cheats (go check the cheat section) for getting 100% in the sequences but for total synchronization you don't get anything.
So if I want the full back-story of repressed memories, I don't need to sweat over not getting 100% on ALL missions then?! I only need to average all my synch enough to get 75% right?! I was afraid I was gonna miss out something if I don't get 100% on all my missions... I've been going back and re-doing every missions I failed and it's frustrating me!! Awesome. Good to know!!
