An unknown newcomer in the anti-piracy scene, called Vigilant Defender, claims to have taken the May 2011 leak of Deus Ex: Human Revolution, added some of their own code, and then illegally rebundled it as an “official” release on various torrent websites.
After playing through the first couple of levels, Vigilant Defender’s additional code closed the game and directed gamers to a questionnaire that quizzed them about piracy: why they download, how much they download, whether they were planning on buying Deus Ex: HR when it was released, and so on.
