This is my second attempt at a walkthrough, so I hope better than the first. You’ll find this is a very direct walkthrough. I will tell you how to get from one place to the other. I won’t turn the game into a book by repeating everything that happens and ruining the game. You obviously want to play the game so I leave that up to you. This means you won’t find any spoilers in here. I seem to be missing a couple of cards and a few secret areas. If you find them let me know and I’ll add them in with credit to you of course.

This walkthrough has 4 sections:

Missions-The main story missions.
Portraits-The 8 portrait missions.
Challenges-Guides and tips for the 3 challenges.
Collecting-All of the hidden goodies (i.e. secrets, cards) not found in the other missions.
