Missions no longer auto-fail if you don’t follow a specific script.  There will be changes and consequences for how you handle the missions,  but that doesn’t mean you’ll be desynchronized. Speaking of being  spotted, the new stealth mode lets you move quietly without sacrificing  your speed, making it excellent for sneaking up on guards. With a new  cover system that makes hiding easier and allows you to peak, it becomes  even more appealing to go full stealth. Once alerted, guards no longer  automatically know where you are – instead, they will search your last  known location, making it easier to get away and even flank them.
