Assassin's Creed 2 Walkthrough

Before you can really start this memory sequence, you need to first collect and have deciphered all thirty of the game's codex pages. They're scattered throughout the many maps of the game, and if you haven't been collecting them you'll need to do a lot of traveling. Though there are thirty codex pages in total, you should already have 14 of them just by playing through the game. The other 16 are distributed between the other cities as follows: Venice - 6, Florence - 5, Tuscany - 2, Forli - 3.

Each codex is in a room guarded by a row of enemies. You have a lot of options when it comes to breaking in past them, including simply killing the guards. If you want to be more subtle, you can hire courtesans, mercenaries or thieves to distract the guards while you waltz in. Alternatively, you can drop a dead body near the guards and they'll move over to inspect it, letting you roll right in behind them.

When you've collected all of the codices, you'll need to have them translated by Leonardo. The game doesn't really tell you so, but Leo's moved into the Villa Monteriggioni, in the same downstairs room as Claudia and the architect. Bring Leonardo the codices and you can then talk to Mario in the adjacent room for the next mission.

Activate the odd glowing thing and then walk up to the wall of codex pages to bring up a puzzle. Use eagle vision and you can spot the faint red outlines of a picture. You need to rotate all of the pieces around into their correct positions in order to complete the picture. Start by going around the perimeter of the puzzle and arranging the border—it's the easiest. Once you've got the border in place, go for the inner pieces.

The pieces should eventually form a familiar map of the world, with the continent arrangements you should know. When the puzzle is complete, so is the mission.

Here are a couple of close-ups to show what the finished map should look like, both with and without eagle vision.
