In order to become an assassin, you have to train. Or, alternatively, you can have your mind uploaded to a machine that tosses it back in time into the body of your Templar-fighting ancestor. That works too. In the trailers for the upcoming Assassin’s Creed, we’ve watched Michael Fassbender’s Callum Lynch jump from roof to roof and leap off of very tall buildings, but before he gets there, he’s got to learn what the Animus is. Marion Cotillard offers him a much too short explanation in this new clip from the movie.
