The Kojima Productions TGS site has gone up, complete with new trailers for Metal Gear Solid: Portable Ops and Metal Gear Solid 4: Guns of the Patriots.

The MGS4 trailer is particularly notable for the long-anticipated revelation of actual gameplay footage, which extensively shows off the new camouflage system, controlling Metal Gear Mk-II, and the utilization of the PS3's tilt sensor. And there's naturally an adequate dose of Kojima humor to pad it out--including a subtle reference to a character from MGS1, of all things.
