Straight from the show floor of TGS 2009, WorthPlaying went hands-on with Metal Gear Solid: Peace Walker for the PSP.
"Metal Gear Solid: Peace Walker is shaping up to be one of the best PSP games to hit the market. While our short demo only gave us a brief taste of the gameplay, what we saw was excellent. The controls were easy to learn and comfortable to use, and it rarely felt like we had to struggle to make Snake do what we wanted. The gameplay is varied and interesting, and while it isn't a perfect port of the Metal Gear Solid gameplay, the changes seem to have done wonders in making the complex mechanics function on the PSP."
