If you have the slightest interest in first-person shooting games, you need to watch this right now. We’ve got two Battlefield 3 videos from E3, and they are simply mind-blowing. First up is a video featuring Dice’s incredible new Frostbite 2 graphics engine. After that, check out a glimpse at some multiplayer mayhem. I’m not an FPS guy, but the footage in these looks like it came straight from a recruiting commercial on TV. I’m impressed, but are you?
