Square Enix is suing a group of 15 "Italian nationals" for leaking a preview build of Deus Ex: Human Revolution to torrent sites a couple of months ago, reports Kotaku. Word is: "As part of court filings issued last month in Washington, Square Enix accuse the fifteen of logging into the servers where the demo was hosted using the access information of an Italian games magazine (GMC), where they found the preview build of the game, copied it and uploaded it onto the internet."
