Ubisoft has released a new trailer from Tom Clancy’s Splinter Cell Double Agent, the sequel scheduled for this September, for PC, Xbox 360, Xbox, PS2 and GC. This time, Sam Fisher is a double agent - to stop a devastating terrorist attack, he must infiltrate a vicious terrorist group and destroy it from within. The game will feature dual objectives to fulfil (NSA government agents and terrorists will each want you to accomplish opposing tasks at the same time), a branching storyline with multiple endings, missions from all over the world (from Asia to Africa to the heart of the US), new authentic gadgets, and more.
