Completion of the trilogy

The game takes place a few years after the end of Brotherhood and sets the knowledge ahead imgrunde. That is why you should definitely play the predecessor to see through all relationships.
It pays to start with AC2 the trilogy, then to play Brotherhood and experience with the end of Revelations.
Ezio has since purged it in a new city, making the atmosphere of the environment is different. The change does the series well, because after two strong parts it's time to turn the Italian life back to see new cities.
The framework of the game remains the same, the mechanics are the same and so we find the AC fan in seconds into the game.
