While we won’t know how they play until we play them, we can judge them today on how they look. Zone of the Enders screens sadly aren’t available yet (that collection isn’t due until next year), but screenshots from the PSP’s Peace Walker and PS2/Xbox’s Metal Gear Solid 2 are available. And are posted in the gallery above.
As is the box art for all three games/collections! As you can see, Peace Walker is being sold as a standalone product, not in the same collection as MGS2 & 3.
