Hi there,
here i am with some interesting new and old (but important) information about Conviction, lets get started..
about the Release date, that we believe it is the last promise they're giving us. Splinter Cell Conviction will be out on 23th Feb in north America, and 26th Feb in Europe. and that if you Have pre-ordered this awesome game you'll have an unique Shotgun in Sam's hands in game. after 6 years of ubisoft Montreal working on Conviction, 2 times team change, and 1 time producer change, 1 time Cover change, 1 time Engine restart, and plus 5 delays, I'm sure that Splinter Cell Conviction wont be only the Best Splinter cell, but it will be the Best game in 2010, other than that we're having the Best game hero on this game, (so many believe so). Splinter Cell Conviction's Musics and Songs, are up toKaveh Cohen and Michael Nielsen that are joining the Groove Addicts music house, which made all the Previous splinter cell song tracks and musics at all. and about Sam's Outfits,After each successful mission, you should be rewarded with a new outfit based on your performance (still a Rumor), and here's a new gameplay videohere. i hope you like it.
Comment how you think, and what your questions are.
Thanks for Reading, Mehrdad out.
