Metal Gear Solid: Peace Walker HD was recently put on Xbox Live for $19.99 and there appears to be an issue. People are reporting that the game is listed there, but is not for sale. It seems that people who have downloaded the game have made numerous reports of major issues when trying to play it. Most likely, Peace Walker was pulled to make patches to the game before it can be released again for purchase. For those of us living in the North American region, hopefully it will be running smoothly when it finally reaches us.
