Much of what we know about Battlefield 3 has come from a series of campaign trailers, and now DICE, the game's developer, has released a variety of assets which illustrate the technology, design, and conceptual work behind what we've seen. Along with the images, the creators included brief descriptions of their process, from audio engineering to storyboarding, which I've summarized beneath each of a selection of the assets below. Check out all of the images in high-res in our screenshot viewer, too.
Above: Several frames of a soldier's animation, which are "seamlessly" blended via ANT tech
Above: Frostbite 2, DICE's new engine, offers the dev rendering features such as "dynamic radiosity, dynamic shadows, and deferred lighting" on "a big scale." This screen shows an area with only the basic lighting information
Above: Here's the same scene, now including "the actual light probes that control how light affects dynamic objects"
Above: ...And the finished environment
Above: Engineering the sounds of a tank
Above: Four images illustrating the improved destruction engine, which can reduce a building's facade to rubble in both single player and multiplayer
Above: One of concept artist Mattias Hägglund's storyboards, which were created to "set the emotional target for Battlefield 3"
Above: Another showcase of Frostbite 2's lighting, and "the physicality of kicking doors in"
