Battlefield 3 looks to be a gritty, darker version of the Battlefields we've played in the past, judging by these first public glimpses of the upcoming shooter from Electronic Arts.

The new video shows in-game footage of U.S. Marines taking on hostile PLR forces in Iraqi Kurdistan. We've seen the game in action and will have full impressions next week.

With this video also comes news that the Limited Edition version of the game will include the digital expansion pack Battlefield 3: Back to Karkand. EA describes the add-on as a "themed multiplayer expansion pack which includes four legendary maps from Battlefield 2 boldly re-imagined with Frostbite 2 physics, destruction and visuals. Completing the package are classic Battlefield 2 weapons and vehicles, unique rewards, new achievements/trophies, and more."
