Let's make one thing clear: Splinter Cell: Conviction is more difficult than you think. When the game's "mark and execute" feature was revealed -- a feature that allows players to target and automatically take enemies out -- some players assumed the game would be a cakewalk. Beyond being one of the more difficult titles I personally had hands-on time with, Splinter Cell: Conviction leads the pack as one of the most impressive titles at TGS 2009. Our meeting with Ubisoft began with producer Alexandre Parizeau walking us through a never-before-seen section of the game before handing us the controller. Taking place "about three-quarters of the way" through the final product, this is the first piece of the real game Ubisoft has ever shown. The E3 2009 demo was developed specifically to showcase Sam's new abilities, but doesn't appear as it did in the final game. This mission's setting: Washington, DC. After living a life on the run, Sam is captured by Third Echelon and brought home. But now, it appears Sam is back on board with his former employers. Whether his return was made voluntarily, forcefully or due to a patriotic sense of duty is unclear. Parizeau and Co. want to keep a few things hidden in the shadows.
