It was back in 2002 when we first met Sam Fisher, a jaded but extremely talented secret agent who was sent all around the world to take care of the most sensitive, covert operations conducted by the United States. Tom Clancy's Splinter Cell became one of the defining franchises of the original Xbox, thanks to its incredibly lifelike graphics and sophisticated stealth action gameplay, and the PC translations of this series have been comparably as good if not better. Earlier this fall, Splinter Cell hit the Xbox 360 for the first time, and the transition to a more powerful new platform naturally created even higher expectations. Yet despite a compelling new premise that forces Fisher to make some tough moral choices to infiltrate a terrorist group, Splinter Cell Double Agent's campaign could best be described as Splinter Cell with a fresh coat of paint. Now this experience is available on the PC in a version that's nearly identical to what can be found on the Xbox 360, notwithstanding some technical issues you might run into. The single-player portion of the game possesses all of the strengths and weaknesses that fans of the series have come to expect. On the other hand, the multiplayer component, which is like a whole separate game, has seen a variety of interesting changes since the last game, making it probably the better half package.
