Ereban: Shadow Legacy's blend of Splatoon and Assassin's Creed releases in April
Stealth games in which you can become "one with the shadows" cover a wide range, though I guess spectrum is the more appropriate word here. You've got sober infiltration games like Thief, which metes out gradations of light and dark with the care of somebody calculating their tax expenses, and stylised affairs such as Mark Of The Ninja, in which stepping into shadow desaturates you and sort of makes your character far too fancy for enemies to notice.
