We've suffered no shortage of Assassin's Creed III trailers, but the latest one actually does finally give us proper insight into Connor's background -- his roots, his journey to Assassinhood.
It's already been established that Connor never intended to really become an Assassin, but he was pulled into the life through some... rather unpleasant circumstances. You know how it goes with these hero-types and tragic happenings. In Connor's case, he lost his home and just about everything he knew growing up.
Appropriately enough, the new trailer is named "An Assassin's Journey," as we get a glimpse of how Connor goes from that frightened child to a skilled killer of Templars.
