Battlefield 3 Teaser..

Seems EA is rolling out the big guns at this years Dice. They released a teaser trailer with gameplay footage showing off the new Frostbite 2 engine. If you pre-order Battlefield 3 you will receive the DLC "Back to Karkand" at no charge. Below you will see captures from the teaser.

In this photo we can see just how clearly design the city is.

A screenshot from the ground in combat.

A view using the gun's aiming system. Notice the blurring effect around the gun.

In this screenshot. We can see how the new frostbite 2 engine handles the contrast of darkness and shadows. I believe this will play into the strategy of the combat.

The solider is dragging another wounded solider. Another part of the gameplay.

Realistic damage can be seen using the new engine.

We can see the combat will be taken to great heights. Also a rocket weapon can be seen.
