The ultimate story of Desmond Miles. The game is well scripted, you will enjoy browsing Boston, New York or even splendid forest. The must of this game, it is the naval battles, which have also encouraged developers to create Assassin's Creed IV - Black Flag.
Desmond is capable of more things, and the parallel story of that character will be more significant than in previous games.
Discover the incredible end of this game, which I personally loved.
