Judging by the demo, this game makes for a much better game than Portable Ops, and will most likely be the greatest PSP game of all-time, hands down. If you have a PSP and have not downloaded this demo to your PSP, you should lay down in a hole and die

It's got the same shooting system as MGS4, 4-player co-op, new characters, and new CQC moves. MGSeace Walkerwill most likely become the most anticipated PSP game, and will most certainly not disappoint you. There's really not much to say except that the Peace Walker demo is the perfect recipe for a perfect portable game. If you'd like to download the demo click THIS.
