GamingLives takes a closer look at Assassin's Creed 3 and, specifically, the naval combat aspect.
"We were shown some of the city of Boston, which had been lovingly recreated to a 1/3 scale for the game and included a number of historical buildings from the time. Here, Connor is given a side mission to free a man from a stockade. Interestingly, the quest giver on this side mission actually follows the player down an ally and distracts the first guard, allowing them to slip past and free her husband."
