WASHINGTON: Freshly leaked documents by former US intelligence contractor Edward Snowden on Monday revealed spies disguised as fantasy characters prowled online games hunting terrorists.

Elves, orcs or other fictional characters happened upon by players in the popular realm of World of Warcraft may have been US and British spies, according to documents released through ProPublica, the Guardian, and the New York Times.

There were also indications that intelligence agents went undercover in online multi-player shooter games, particularly on Microsoft’s Xbox Live Internet community for players.

“GVEs (games and virtual environments) are an opportunity!” concluded ‘top secret’ National Security Agency documents dating back about five years.

“We know that terrorists use many feature rich Internet communications media for operational purposes, such as e-mail, VoIP, chat, proxies and web forums, and it is highly likely they will be making use of the many communications features offered by games and virtual environments.” The report depicted online game worlds as private meeting places that could be used by groups for planning and training.

Examples used to back the reasoning included an “America’s Army” shooter game made by the US military and given away as a free download at its recruiting website.
