In my opinion the best Splinter Cell to date.
Graphics: 9/10 Some bland textures but other than that the game looks gritty but colorful and very smooth animations.
Sound: 10/10 The explotions, the silenced pistol in your hand, and the crack of jumping out the window seams like a movie. Voice acting is Top-notch.
Story: 9/10 The best in the series for it is much more grittyer and the story telling is excellent. If this is the last series, i dont know.
Gameplay:10/10 The best part of the game. The story if pretty short at around 5-7 hours but it is one sweet SP. The MP features Prologue, spy vs spy, and other modes. It is addicting and very co-operative.
Enjoyment: The best in the series and must be played by Splinter cell fans, action game fans, and Stealth fans alike.
Overall: Just go buy this right now.
