I guess I am just missing what everyone else is raving about. The game play is clunky, as is the field of vision, and the combat even more so. The stealth/mercy playstyle is no longer rewarding and is more just painful than it is hard. The game is passable if you wish to have a violent playthrough but that is not what you are there to do.
On a positive note rhe ambiance and graphics are fine and the game redeems itself with a decent story, voice acting, and narrative. However, actually playing this game is simply not enjoyable, and quite frankly it is simply one of the worst combat/environment interaction systems I have seen in a modern stealth game.
Unfortunately this game not only does not live up to its predecessor, but it hardly qualifies as a passable game in the genre it helped establish.
