Grand pappy Snake’s next portable adventure, “Metal Gear Solid: Peace Walker,” is meant to be a full sequel to “Metal Gear Solid 3,” with traditional “MGS”-style gameplay, unlike “Portable Ops.” But don’t take my word for it. Konami is releasing a demo for the game on PSN today, allowing folks to get a taste of the title on their PSPs before the release in 2010.

So yeah, go take a look. Just try to avoid those pesky time paradoxes.
