Well since Splinter Cell Conviction has all but been delayed I guess this would serve well as an alternative.
_Robert Ludlum's The Bourne Conspiracy gives players the experience of becoming a 30 million dollar elite agent, combining elements that delve deeply into Jason Bourne's character with gameplay and game presentation informed by the style of the films. The game does not use the likeness of Matt Damon who portrays Bourne in the films. As the game progresses, players are provided with more clues to Bourne's true identity and begin the game by first hunting targets around the world as a deadly government assassin then labelled the agency's most wanted.
Players use Jason Bourne's sense of survival, cunning nature, heightened target awareness and firearms training to engage and eliminate small armies. As a third-person espionage action game, players move from fistfights to firefights to experience sequences that aim to seamlessly blend Bourne's signature hand-to-hand combat with intense shooting and the ability to escape and evade deadly situations._
I played the demo twice and while it was iffy in some minor regards it was fun the embassy mission in particular also the takedowns are just crazy.
