A new Assassin’s Creed Unity in-game cinematic trailer had made its way, it is about the training of Arno Victor Dorian (The Protagonist of Assassin’s Creed Unity). So the trailer starts when Arno wakes up in the prison and a guy (who could possibly be his mentor) holding the 18th century watch of Arno (the watch show in Elise trailer). An angry Arno asked him to give him the watch back, but the guy said he wanted to fight and if Arno wins he will get his watch back. Then the trailer skips 2 months forward where the guy is training Arno. A small earthquake, then happened when Arno look outside of the window he sees (possibly the third estate) attacking the prison Arno is (maybe the Bastille prison) and the trailer ends.
OK, so the description ends with the first paragraph and I think I figured out the early plot of the game. So as we all know Arno first father who was an Assassin died when Arno was a child, then Arno was adapted by a Templar grand master and Arno also have to deal with his second father’s daughter Elise. Now when his second father, died the same way Arno’s first father died and with no proof or evidence so Everybody framed Arno. Now here this Arno training trailer gives us the last part of the early plot. Arno then must have met that guy who is an Assassin in the prison and possibly his mentor and to find his father true killer Arno trained with him and after the third estate attack on Bastille prison they both escaped to Assassin’s Headquarters and Arno trained there and became an Assassin.
One more interesting thing to notice the watch Arno is holding in the Elsie trailer and this trailer is similar and it is must have been given to him by Elise who is a Templar in the game and Arno’s romantic interest. That’s why Arno got angry when the guy took that watch because he loves Elise. Well, but what I had written in the Second and Third paragraph are nothing but a theory and possibility now I believe 80% that this is the early plot.
Assassin’s Creed Unity will release on November 11 for Microsoft Windows, Xbox One and PlayStation 4.
