Hm. It do be a tech demo, lets make sure we get that out of the way first. Game's like one mission long, which I'm honestly fine with and the level is pretty cool all things considered. This game tries to go for a much darker sort of vibe than what usually goes on in metal gear, and theres some kinda gross scenes that are made grosser by the shiny photorealistic new FOX engine they got going here. Doesn't exactly end on a very positive note either, but I guess that's to set up the Phantom Pain. All in all, don't buy this on its own since there's not enough game here to be worth any price on its own, but if you wanna play phantom pain, you should probably play this first to understand whats goin on
