The first screenshots of Battlefield 4 have surfaced ahead of the game's announcement later tonight at the Game Developers Conference 2013, where DICE and Electronic Arts plan to unveil the game to the public for the first time ever—hopefully with some actual gameplay.
In any case, the single-player campaign of Battlefield 4 appears to be set in China, and offers the same art style as its predecessor, Battlefield 3. The game maintains its "gritty, realistic, serious" presentation of war with a modern day setting and doesn't veer off course with comedy in the way the Bad Company spinoffs did.
Battlefield 4 is being built upon a brand new engine called Frostbite 3, and is—as far as we know—the only game currently in development on the next-gen engine. As you can imagine, the engine is being developed for the PC and next-gen platforms including the PlayStation 4 and its counterpart at Microsoft.
The screenshots show the new technology in action, depicting large scale battlefields, and a cast of characters with some of the most realistic faces we've seen in a videogame to date. David Cage is going to get a run for his money when he sees what DICE has cooked up.
