Simply Awesome Splinter Cell Game to the Bone
I'm in my third play-through and I just love this game. To put it short, go and buy it...seriously.
Pros: 'Mark and Execute' really shows that Sam has matured from a loyal by-the-books super-spy to a 'Jason Bourne' type or rogue agent killing machine. The light meter is replaced with the screen going black-and-white when invisible/undetected. The fast-paced game has a variety of guns and mods to choose from. Graphics is great, fluid frame-rates to facilitate the non-stop action. The approach of completing missions has also been diversified; every environment has so many ways of disposing your enemies. Having this said, considering how awesome the game is, the replay value is very high.
Cons: ALSO the 'Mark and Execute'; it just killed what we (the SC fans) used to know about Splinter Cell, which is all about stealth and avoiding alerts and firefight confrontation. Rather challenging even at Normal as this feature requires a rather steep learning curve for SC fans who've been playing since the 1st game, so a lot of adjustments to the style of Sam's approach has to be made.
Overall, this game is still great and totally worth your time and money as you'll be playing it again and again! It's just so addictive being Sam in this game!
