The shooting itself is average: not too bad, but nothing new. It's the storyline that's awesome!
The graphics are pretty cool, because in a semi-animated world, all the people are animated. It's a nice touch.
The gameplay is good. It actually reminded me of 007 Nightfire, but with the long awaited (though animated) blood and violence effects. The weapons are also standard, your fists, a throwing knife (with a melee atack option), two pistols, two rifles, an SMG, two machine guns (including the Kalashnikov aka AK-47), an RPG, a heavy machine gun, grenades, a sniper rifle, and (the coolest!) the crossbow. You can also use lots of things you see in the environment.
You also have a number of gadgets from a grappling hook to a lockpick.
All in all, it's fairly good. You may want to rent it as I beat it in three days, but to enjoy it, you need to play it at least three times.
