Awesome mixture of 3rd person shooter, adventure, action and stealth, with a great story to boot.
The story is great. The story telling is awesome, and it hooks you in it instantly. This is one of those games that you don't really want to put down because of the story. Infact, I'd go as far as to say that the story is one of best I have seen in a long while. It's well supported by decently casted voice talents, and because it's a very story driven game in the end, it's a blessing that the cast is as good as they are.
Controls are quite good. It's apparent that the console origins are there, but there really isn't anything else to complain than the camera, but even that is only troublesome at times. Biggest problem with it is that it doesn't go through walls. Because of this, it sometimes creates quite interesting, but useless, camera angles. If the camera could go through walls (and the wall would then turn transparent, of course, so we could still see the playable character), there wouldn't be a problem like this. But in the end, this is not so big of a deal.
While some may say that the graphics are simple and ugly, I personally liked the comic style. It looks personal and interesting, not of the same mold as 99% of the games are these days. Musics and sound effects were quite okay. Graeme Norgate did quite a few memorable songs for this, it's too bad that there is no soundtrack available.
The game offers two difficulties, and while the normal one is quite fine for me, the challenging one will provide something extra for seasoned veterans.
All in all, this is very very good game, with interesting story and good gameplay. Definitely worth checking out.
