There was a mission in Assassin's creed 2 where you had to kill Savonarola's 9 lieutenants. One of them, the merchant, was stationed on a ship, and had many guards on the ship patrolling constantly. I was wondering if there's any mission in assassin's creed unity like that.
Well I'm gonna answer as honestly as I can.
In one way NO there is no mission like that because the game is set in the French Revolution in Paris so there were no boats/ships like that there. So in that sense there is no mission like that.
In the sense that there were many patrolling guards the game features a lot of missions that require really good skills in stealth and require you to blend and be a blade in the crowd.
Unity completetely increased the amount of guards patrolling in missions and many people consider the game harder because of that.
