WarGames: The Dead Code (2008)

A brilliant hacker inadvertently sets the wheels of World War III into motion after hacking into a restricted online gaming network and learning of a national defense system designed to identify fledgling terrorist cells in this belated sequel to the popular 1982 thriller. There isn't a system on the planet that Will Farmer (Matt Lanter) can't hack into with a little work, so when he manages to breach the security of a restricted online gaming network known as R.I.P.L.E.Y., he's convinced that his skills are still as sharp as ever. But what Matt hasn't realized is that R.I.P.L.E.Y. is actually a highly classified government defense system, and he's just become its next target. Now the system knows his identity, and his entire hometown faces the threat of an automated military response. In order to clear his name, Matt will have to beat the computer at its own game. The game turns deadly, however, when R.I.P.L.E.Y. suddenly raises the stakes, threatening Armageddon in a time when the world is already dangerously unstable. With no time left to lose before the missiles start to fly, Matt must now use his formidable hacking skills to save the world from the government's own hopelessly flawed doomsday device.
