There's a good 12 minutes worth of gameplay footage captured during Hideo Kojima's Metal Gear Solid 5: The Phantom Pain demonstration at the Tokyo Game Show. It took place at Sony's PlayStation booth.
It shows off a good slice of Snake doing what he does best, although it's a little noisy with Kojima-san and others talking over the demo. If you need busting out a camp, Snake's your guy.
Earlier Hideo Kojima had warned MGS fans the he might not be able to complete the presentation during TGS because the AI behaves so erratically at the moment.
Metal Gear Solid 5: The Phantom Pain releases on Xbox 360, PS3, Xbox One and PS4 in 2014.
