Just finished it. Got the Altair outfit, Auditore Crypt (secret map) and a 360 theme from UPlay too. A few questions though..
Spoiler (highlight to read):
Why does it take 5 times to defeat Borgia... and he's STILL not dead after it all? And what, we were made by aliens? And finally, what happened to DNA sequences 12 and 13? Why do you just skip over them?
Oh and, how do I get the Auditore cape? Or is it the plain brown cape? In my inventory there's one outfit that still hasn't been unlocked... dunno how to get it or if it's the Auditore cape itself.
The last achievements shouldn't be too hard. The feathers will be a pain but whatever. I've got 840/1000 now.
