DICE came on stage during Microsoft's E3 press conference earlier to show off a new single-player demo for Battlefield 4. It featured huge set pieces inside and eventually on top of a battleship, beautifully presented in the new Frostbite 3 engine. If you missed the demonstration, DICE has released the entire demo playthrough as the "Angry Sea" trailer.
If you weren't impressed by the stream quality, the trailer is available on YouTube in 1080p, and it looks quite nice (and yes, we noticed the backspace button at the top-right corner). If you're still not convinced, DICE also released four new screenshots that show off just how pretty the game really looks. Those lighting effects are really something.
