Handheld game developer Torus Games' first PlayStation 2 title is a first-person shooter that follows the story of CIA operative James Clayton on his first assignment. The title refers to a computer virus with the power to devastate the world's financial institutions and corporate network should it fall into the wrong hands -- which in this case means Xu terrorists. Taking a page from such titles as Metal Gear Solid, Hitman 2, and Tom Clancy's Splinter Cell, Ice Nine emphasizes stealth in completing mission objectives, many of which involve obtaining disguises to bypass security.

Clayton begins the game armed with a silenced pistol, but will over the course of his assignment be able to acquire and use assault rifles, grenades, sniper rifles, and mines. The character also carries with him a PDA to download sensitive files from the computers he encounters during missions, allowing him to download codes needed to access certain areas as well as giving him the evidence he needs to bring down the terrorist network once and for all. The world in Ice Nine is designed to be fully interactive to the point where players can manipulate boxes, furniture, artwork, and more to solve puzzles or to reveal hidden areas. ~ Scott Alan Marriott, All Game Guide
