Ground Zeroes, a Metal Gear Solid V movie

Ground Zeroes is a trial run for the large open world stealth/action game The Phantom Pain, yet it still shines as a stand-alone, incredibly replayable stealth level. You must enter a blacksite as the sly commando Snake to release inmates and learn more about the actions of the skull-faced bad guy. In terms of plot, it's nonsense, but Ground Zeroes is a terrific short alternative to the massive (but equally fantastic) Phantom Pain if you're looking for a strong systems-driven infiltration sandbox.
