According to the tweet, Race & Revenge are the related themes. Could this mean some sort of Race against time in Ground Zeroes with Revenge being the overarching theme in The Phantom Pain, or perhaps something a little more complex than that? Somehow it seems more probable that it will be the latter.
Comment on what you think the themes for Metal gear Solid 5 mean and how the two relate to one another.
