Although at first this game may be compared to the ever-popular GoldenEye, once you start playing it, you'll definitely realize that this game is along a different line and will make a name for itself.
The interface itself is very clean and easy to learn. It may take a while to get used to the fact that almost anything can be tried. The enemy AI is pretty good, and your own actions can dictate their attitude. Sneaking around is a good way to avoid unnecessary gunfights. Keep your cool while walking around, and you might be able to avoid alerting guards around corners or in rooms. The impossible level of difficulty mainly changes the amount of damage that you can sustain.
Note: The text in orange represents an objective that is only available in the impossible level of difficulty.
