Prefer the artful headshot of the sniper rifle to the scorched-earth carnage of the gatlin gun? Good, Britain's GCHQ needs your help. The intelligence service focused on securing communications and information systems is set to embed adverts in games like "Tom Clancy's Splinter Cell: Double Agent" starting this month. A GCHQ spokesperson told The Times that the move was a bid to attract "computer-savvy, technologically-able, quick-thinking" recruits. The advertisements will not be written into the games themselves but will be fed via the Internet to PCs or Xbox 360 consoles. As the expression goes, "Never trust a gamer under 30."
