Unlike many games, collecting Afro Samurai's Mementos is much more than a means to boost your Gamerscore. Mementos are the keys to unlocking some of the most devastating combos in the game, and in turn, the combos are going to make the aggravating boss-fights a little more manageable. Don't you love it when two design elements work together so perfectly?
This guide is broken into in-game levels. From there, the Mementos are listed in chronological order. After the Mementos of each level, you will find strategies for any noteworthy boss-fights in that level.
