Activision has announced the 2014 instalment of its first-person shooter series, Call of Duty. The new game, titled Advanced Warfare, will be out on 4 November. The game is being developed by the San Francisco-based studio Sledgehammer who previously worked on Modern Warfare 3.

The game will feature the Oscar winning actor Kevin Spacey as its lead antagonist and videos of him and the game are causing much excitement on social media. Advanced Warfare will feature Spacey as the head of a private military contractor who goes rogue against the US government.

Spacey is most recently famous for his role as the heinous Frank Underwood in the Netflix political drama series House of Cards and fans are looking forward to him upping the ante in the game as he does in the show. Spacey also appeared in the Xbox 360 and PlayStation 2 games of Superman Returns.

The Guardian reports that Activision initially intended to slowly release news of its next blockbuster through snippets of information. But last week it announced a teaser site and further revelations to come on 4 May. It has also released a documentary short on real-life private military contractors and their role across the world.

Fans have been glued to the Internet to search for more specifics this week, after Call of Duty tweeted, "#ANewEra of Call of Duty arrives May 4th," along with a link to a secret, 12-second teaser.

The teaser shows Spacey saying, "Ideas don't determine who's right - power determines who's right. And I have the power, so I'm right."

Super sleuthing by fans on the Internet has gone to the extent of speculating that Activision had hidden an image of a soldier carrying a rifle in the sound file of the Spacey teaser, after Yahoo analysed the clip with a Spectrogram.

Gary Oldman, Ice Cube, Sam Worthington, Ed Harris, Snoop Dogg and Kiefer Sutherland are just a few of the actors and singers that have voiced characters in the Call of Duty game over the years.

The Call of Duty series has sold over 100 million copies since its first instalment in 2003. The most popular chapter has been Call of Duty: Black Ops II in 2012, which generated over $ 1 billion in revenues after just two week of its release. In 2013 Call of Duty: Ghosts sold almost 20 million copies, becoming the second highest selling game after Grand Theft Auto V.
