Titled 'Making a Masterpiece', the first part of the Inside Assassin's Creed series looks at what it takes to create the game from the ground up.
The video sees members of the development team discuss the amount of time and effort it takes to complete such a massive undertaking.
The team then talks about the period in which the game is set, as well as the new protagonist, calling him a "defender of the people" after demonstrating the voice recording process.
Officially unveiled in March, Assassin's Creed 3 will take place over a 30-year period in colonial America beginning in 1777.
It features a brand new lead named Connor, the offspring of an English father and Native American mother.
