Ubisoft have been doing an abjectly poor job at properly telling players what to expect from Splinter Cell: Blacklist. We know full well that it supports stealth and action simultaneously and lets you choose between them as you see fit, but you wouldn't know it for all the trailers of big explosions, air strikes and cover shooting.
That said, things are picking up. This new slice of alpha footage may be short, but it showcases pure stealth gameplay faciliated by the 'Closer Than Ever' mechanic. Expect more over the coming weeks.
