Dedicated stealth button should be a godsent. (having just played a fair amount of MGS5 Ground Zeroes, the stealth on display here still looks pedestrian at best. Besides, if this is anything like the stealth in every other recent Ubisoft title, it'll be a hundred times easier to just fight your way through the game anyway, so what does it matter) Still, as gorgeous as this looks, it also looks strangely clumsy and mechanical, especially when compared to the gloriously slick footage of Arkham Knight.
1:1 scale reproduction of Paris though - that is pretty impressive.
