Great game, very enjoyable.
Good Points:
Lot's levels, which is always good especially when it comes to objective games. The animation is smooth when moving the reticule around and it's never hard to shoot anyone. The de-briefing is always good, it establishes the story as in-depth as it can, but this necessarily isnt good.
Bad Points:
The opening scene where he is punching the guy, the art isn't as good as it should be, considering how good the gameplay. It seem's you didn't put as much effort into the movies as you did the gameplay. The art for the scene needs to be improved greatly and perhaps more added to it. When you shoot certain civilians, it just skips straight to 'mission failure' and this seems like you just lazed out on the killing sequences.
Overall:
Very good game, lots of varied levels and different things offered since the second installment, many things to consider though until it is perfect. Good job.
