A little late for some people - but this was a huge one to get done.
We've uploaded a complete guide for Assassin's Creed II here:
AS well as a complete walkthrough of the game, every one of Ezios memories is covered in this guide, as well as every optional event, feather location, and Monteriggioni statue location. You will also find solutions to all 20 Glyph puzzles and video walkthroughs for each Assassins Tomb.
There are over 70 videos in total for this guide - it's huge and we hope you enjoy it.
