This year's Call of Duty focuses on private military contractors, will be revealed May 4

[UPDATE] A new video from Activision and Vice offers more information about this year's Call of Duty game. "In the next Call of Duty, the world's most powerful military is not a country," the video says. "It's a corporation."

"In the last 20 years, global combat has seen a steady shift towards the use of private military corporations, or PMCs. What happens when the highest bidder becomes the world's next superpower?"

"A new era of Call of Duty is coming," the video closes with.

The original story is below.

Activision today launched a teaser website for this year's Call of Duty game, in development at Modern Warfare 3 co-developer Sledgehammer Games. The website tells fans to "Get ready for a new era" of Call of Duty and that the game will be revealed on Sunday, May 4.

A countdown clock on the teaser website ends at 1 p.m. EDT on May 4. The rest of the website features an indiscernible flickering image. The website's source code reveals the image below, which appears to showcase San Francisco's Golden Gate Bridge.

Earlier this month, we got our first look at a character model for this year's Call of Duty game. We don't know anything about the plot or features for the game, but Activision has high hopes for the project, labeling it "ambitious" and "creative," as well as "perhaps the best Call of Duty game ever created."

Game Informer will showcase this year's Call of Duty game for its next issue. The magazine has also obtained the game's first screenshot, which shows off a soldier in some kind of mech-suit. The magazine also says the game's first trailer will go live May 4 at 1 p.m. EDT. We will have all the Call of Duty news for you this weekend as it happens.
