Well, i was looking on the internet for some AC2 infos and found out that there is no Memory Sesquence 12 and 13, but also, there is 2 DLC for consoles (didn't see it for pc) and the especial editions says to have bonuses missions called "Templar Lairs"... And something curious, some people keeps saying that they only can get 97% of the game complete, why is this?

There go my questions: 1) About the sequences 12 and 13, what it is? Is there any way to play it? 2) The 2 DLC, "The Battle of Forlì" and "Bonfire of the Vanities", are they playable in pc? I have to download it? Is it on every edition of the pc version, or only in black/white editions? 3) The templar lairs are playable in the regular editions? 4) And the 97% com game completion, how to get it 100%?
