With just over a month to go until Assassin's Creed III's launch, Ubisoft has released the fourth 'Inside Assassin's Creed III' episode today, looking closer at the accuracy of the historical aspects of the game, from the colonial cities of Boston and New York - complete with roaming pigs - to the Frontier and the high seas.

There's a dynamic weather system along the day/night cycle in AC III too, so you can sea the seasons change around you. In the Frontier meanwhile, you'll have to cope with humidity, cold, snow and an ecosystem of animals, as well as the organic environment comprised of trees and rocks.

Finally, there's more about the Naval Warfare, which involves the French, the Spanish and Dutch as well as the British and American forces. It's all suitably epic stuff, and the trailer offers up additional historical insight into the game as well as another look at Assassin's Creed III in a bit more detail.

Watch the video below, then look out for Assassin's Creed III on October 30th, 2012.
