You’ve seen the trailer, now see the gameplay. They actually modeled Sam Fisher on a younger, fitter now-CrunchGear-editor John Biggs. John was never quite that deadly, let’s be honest, but we have to allow a certain level of artistic license in these things. The lithe movements are very Biggs-ish, though.
Seriously, though, it looks pretty cool. I think they’ve sacrificed immersion for a more cinematic approach, and of course stealth has kind of gone out the window in some ways, but it still looks like a really compelling game.
