So if stealth is included, how do we think it will work? Will you be able to lie prone and crawl throuhg vents, shooting through the grates? Will we be able to use a cover system? How do we want stealth.

I think it'll be like cutting someone's throat from behind, but if you make a single sound, an AK-47 bullet to your head.

Ehh there's a silenced pistol and a sneak one hit kill melee move if you sneak up from behind and you can unlock one to do from the front that's about it but the game gives you a lot of option as to which style you want to use.
