IGN: "Then, the sound started -- an echoing loop of gunshot noises and ambient action -- and everyone knew something was wrong. Some people scrambled, some tried to ignore it, but eventually the mucked-up sound ended the trailer before anything new was shown. Instead, the room just saw the same ol' soldiers fall to the ground and begin writhing in pain before the lights came back on.
Kojima shrugged, went on with his presentation and hinted that he had a special guest from Japan for tomorrow's Metal Gear Solid 4 conference. Hopefully, he'll have a cooperating trailer as well."
