Kojima has confirmed via Twitter (with picture to boot) that MGS: Peace Walker HD will have online four player co-op on Xbox Live and PSN, and will run on 60FPS.
“4 people can co-op and it is 60 frames. During loading, characters’ dialogues pop up at random,” Kojima tweeted.
MGS HD Collection, which includes Peace Walker’s HD re-release as well, will release in November for the Xbox 360 and PS3.
