Unlockables and Trophies | Assassin's Creed III Wiki

While the modern AAA title is expected to include a proper list of Achievements/Trophies that revolve around actions that the player completes in the game, increasingly the trend has developed to include special unlockable trophies inside the games, often with these special items serving as the focus of decorations in the player-characters home/lair (or both) and following a theme that is related to the game subject and setting. Assassin's Creed III has really embraced this model and trend, offering the player a plethora of different trophies with which to decorate their home (the Homestead Manor House) as well as their Lair (the Secret Assassin Lair in the cellar of the Manor House) spanning several basic systems / mechanisms.
The collection items are broken up into 4 categories, as follows:
The Collection System Rewards are obtained for completing specific Collections that are part of the process for obtaining 100% game completion anyway, so you will very likely be wanting to do these for that reason, making these rewards a bonus to the process!
These are actually a sort of nested set of rewards since they lead to other rewards that are obtained via the Crafting System, but essentially this starts with the collection of Almanac Pages and Treasure Chests...
On each of the city maps there are loose Almanack Pages that the player needs to collect in order to complete (and re-assemble) their related books, which once completed are then displayed on a large bookshelf and display case that is placed in the player-character's bedroom at the Manor House after the first one is completed. The individual collections are:
After you collect each set of pages the book is automatically re-assembled and then appears in the bookshelf and display case in Connor's Manor House Room. In addition to adding the book to the display in his room, when you complete each of the books they provide you with one or more of Benjamin Franklin's special crafting recipes!
With those, and assuming you have been diligent about completing the Homestead Missions and thus recruiting settlers (read that Crafters) to the Homestead, once you have leveled the Homestead Crafters to their top level (by completing their related missions) you will be able to obtain all of the raw resources required in order to craft the recipes for Franklin's creations, which are displayed in a dedicated room in the Manor House.
In addition to the craftable recipes and the display of the crafted items in the Manor House when you have completed Sequence 12 you will also receive a famous painting of Franklin, which will be displayed in the room as well – that is called the Ben Franklin Painting.
The recipes that you can obtain and eventually craft include:
Once you have these recipes there is no timer running on when you can make them, and of course you have to advance the crafters that are related to each to the minimum level required, so basically you are going to want to set aside your eagerness to get these added to the Manor House until such time as you can actually do it. Still, you should be sure that you make the effort to collect the recipes by completing each mission/quest/collection since some of them will disappear if you don't do them during the Sequence that they appear in (particularly the Homestead Missions).
These rewards are pretty much attached to the different missions in which they are obtained, and as many of those are miss-able, you need to stay on top of completing the optional missions as well during the time that they appear in the game which is based on the Sequences.
The following mission-related rewards appear in the game:
= Story-related Rewards =
This may seem a bit confusing but it is not really - these are basically rewards for completing the different story elements completely - so each Memento/Trophy will unlock when you do that. So just play through the story and be sure that you complete all of the goals for each Sequence to unlock the following trophies:
These are supposed to be related souvenirs that bring the events to mind...
– Newspaper Rewards –
These appear on the paper table in the sitting area of Connor's room at the Manor House...
– Other Rewards –
In addition to the above there are other reward trophies that take the form of paintings, maps, or objects, and these are:
= Homestead-related Rewards =
These are basically rewards that are related to the Homestead and Manor House...
Once a reward has been unlocked it can be found in its proper place in the Homestead Manor House with the exception of the Benjamin Franklin Recipes, which you have to first level the crafters of the Homestead to the point that they can supply the required resource and are of the level required to craft it, at which point and having crafted the recipe, it can be found in its proper place in the Franklin Room in the Manor House.
