New batch of screens/videos and hands on preview within. Some excerpts:
Speaking of guns, Metal Gear Solid 4's arsenal options are already setting new standards. The game includes over 70 unique firearms, with an array of pistols, sub-machineguns, rifles, shotguns, and far, far more. Gun modifications are another bright spot in MGS4. Through a sleek 3D interface, we outfitted a basic M4 assault rifle with a laser sight, red-dot scope, flashlight, under-barrel grenade launcher (shotgun also available), plus a silencer. That's five upgrades attached to one gun -- astonishing! It's a minor miracle that the aging Snake is able to even heft that bulky, do-it-all firearm, let alone shoulder and fire it. In another realistic touch, you can set automatic weapons to single-shot, triple burst, and full-auto modes. Naturally, Snake's still got a full repertoire of close-quarters maneuvers, from basic hand-to-hand combos to silent strangleholds a la MGS3. The end result is an extremely versatile combat system that's loaded with replay value.
Playing a nearly complete build of Metal Gear Solid 4 running on the PlayStation 3 was a revelatory experience. The graphics looked sensational, the sound effects and music sounded magnificently epic, and the interface felt sleek and simple. In short, it's becoming increasingly clear that Metal Gear Solid 4 will be the rare game to live up to its own massive hype. We feel confident that MGS4 is the game PlayStation 3 owners (and Metal Gear fans) have been waiting years to play.
