All About MGS: Peace Walker's "Co-ops"

Metal Gear Solid Peace Walker, a game that's had more than its fair share of hype over the past couple months, is getting its big, fancy public debut at the Tokyo Game Show as you read this. If you're lucky enough to be in Makuhari for the event, you can bring along a PSP (don't forget to update your system software and clear out 200MB on your Memory Stick first) to download the three-mission-long, multiplayer-ready Peace Walker demo to your system for free.
