Battlefield 3 developer Dice has made a blog post with new details about the game's multiplayer maps.

The post includes design insights from level designer Niklas Åstrand and reveals three new maps called "Operation Firestorm", "Tehran Highway" and "Damavand Peak", in addition to covering the "Operation Metro" map already familiar from the open beta.

"The nine multiplayer maps in Battlefield 3 offer every style of gameplay from dense urban combat to all-out vehicle warfare on vast landscapes," says the post.

The remaining five maps will be revealed tomorrow.

Operation Firestorm

Working title: Oilfields
Dice internal designation: MP012
Supported game modes: All
Brief: All-out desert warfare

Fiction: U.S. and Russia launch large-scale assaults to control Iran's biggest source of oil. Securing this area will offer full control of the sector and its key facilities.

Niklas Åstrand's design thoughts: One of our largest and most vehicle-friendly map, Operation Firestorm is the classic Battlefield gameplay taken to the extremes. Size-wise, and with some puzzle skills, you could actually place three Atacama Deserts – one of the largest maps from Battlefield: Bad Company 2 – within the playable area of Operation Firestorm. This is a wide-open desert map where the burning oil fields in one direction are contrasted by clear blue sky in the other direction. Construction sites dotting the area bring interesting possibilities for infantry to hide in elevated positions, spot vehicles, and take them down by mortar or RPG.

Operation Metro

Working title: Metro
Dice internal designation: MP015
Supported game modes: All
Brief: Infantry focused combat in subway

Fiction: Heavy fighting is expected as U.S. forces push to secure the financial district in central Paris. Russian anti-air emplacements in Chardonnay Park are likely to be the first target.

Niklas Åstrand's design thoughts: Operation Métro is the map from E3 and the Open Beta, so some of you are familiar with it already. It is a map that perfectly illustrates that we want to take our players on a journey. Especially in Rush, you can see how Operation Métro is almost three maps within one: You start out in a lush park, then move into a bombed-out section of the subway tunnels, to finally emerge in a dense urban environment outside the Paris stock exchange. It’s a map that asks you to constantly adapt your class and load out for the diverse situations you will find yourself in.

Tehran Highway

Working title: Highway
Dice internal designation: MP003
Supported game modes: All
Brief: Infantry fighting in tight city streets

Fiction: A fight for control of access routes near Tehran. U.S. forces make a push from the hills under cover of darkness while Russians have set up defensive positions along the main entrance points.

Niklas Åstrand's design thoughts: One of the inspirations for this map was a photo of a night time skyline of Tehran which now is basically the same vista that is available in the game. You start up on the hills above the city outskirts and eventually work your way into town. This atmospheric night-time map, where you can see rockets lighting up the sky, has a balanced mix between vehicle and infantry focus. It plays length-wise and starts semi-open with plenty of room for vehicles, but ends on a much more urban and tight note with less focus on vehicles and more on infantry.

Damavand Peak

Working title: Base Jump
Dice internal designation: MP013
Supported game modes: All
Brief: Fighting in winter mountains

Fiction: A rugged mountain area plays a major role in deciding whether Russian or U.S. troops are successful in combat operations in the sector, as the area is home to key radar installations.

Niklas Åstrand's design thoughts: Damavand Peak, internally known as Base Jump, is built on the idea that we want players to be able to base jump, and features our most extreme height differences ever in a Battlefield map. Attackers in Rush and Squad Rush will start high up on a mountain ridge above a mining facility. The only way down into the valley is to somehow make the 500 meter descent. The further the attackers progress in the map, the more vehicle warfare will be present. There is also a large tunnel section dug into the mountain side at the bottom of the map, and the view when you look up at the starting location is spectacular.
