It came out like 2 years ago... but it's still awesome
The graphics are really good, the shadows are just awesome and character models look good too.
Now, on to the gameplay. There's a lot of cool gadgets at your disposal which yu can use to lure your enemies out in the open, stun them, or even kill them (although I feel they were a lot more useful in Chaos Theory). Hacking has been improved , and now it's a lot more easier and simple; lock picking remains the same though (something I didn't like is that once you get the electronic lock pick, you can't change back to the standard ones). You also got some cool new moves, such as dragging enemies into the water through the ice to stab them in the heart
You got plenty of different objectives which assure you won't be doing the same every time you play, there is as well, a good variety of levels, a Hotel in Shanghai (My personal favorite), a boat in Cozumel, Iceland, a war zone in Kinshasa... as i said, it's a good variety, sadly, there's only a couple more levels, so the game seemed a little short to me. Something I also noticed is that you'll rarely have to use any of the special visions, such as the night Vision or the Thermal Vision.
there are a couple of missions in the JBA HQ, in which you're given a set amount of time to complete a couple of objectives for either the JBA or the NSA. These missions are kinda lousy, because they mainly consist of boring mini-games that will soon become tedious, specially the E-mail hacking mini-game....
I really can't say anything about the multiplayer, because although I bought the game as soon as it came out, I never played the multiplayer until recently, and there was absolutely no one in there, but it looks pretty decent since I could play with the computer (Although, i must state I didn't like the new models of the SHADOWNET agents).
Overall, it's a really good game, but you must like its stealth gameplay to really enjoy it, otherwise you'll find it boring. But as far as i'm concerned, it's awesome.
