Konami today debuted a new trailer for Metal Gear Solid 4: Guns of the Patriots, for the PlayStation 3. Here's a little bit about the trailer:

Metal Gear Solid 4: Guns of the Patriots features an aging and exhausted Solid Snake in the middle of a futuristic battlefield. In spite of his failing body, Snake is equipped with a crucial new device tentatively known as “OctoCamo,” a high-tech suit that dynamically transforms its texture based on Snake’s surroundings. This revolutionary new gameplay mechanic allows him to seamlessly blend into the environment, providing him with the means to stalk his enemies like never before. The trailer marks the return of several characters from previous Metal Gear Solid games including Revolver Ocelot, Meryl Silverburgh, Naomi Hunter and Raiden, setting the stage for an unforgettable story that depicts the desperate state of the future as seen through the eyes of an older Solid Snake.

The new Metal Gear Solid 4: Guns of the Patriots trailer will be shown every hour at Konami’s booth at E3, but we're guessing we'll be able to dig up some footage for you before too long.
