Ground Zeroes

For full info on MGSV: Ground Zeroes, visit the Metal Gear Wiki.Taking place after the events of Metal Gear Solid: Peace Walker, Ground Zeroes serves as a prologue to Metal Gear Solid V: The Phantom Pain, with Big Boss returning as the game's protagonist. Several characters and gameplay mechanics from Peace Walker have returned.

Metal Gear Solid V: The Phantom Pain saves a copy of its play records and save data to the Ground Zeroes folder, as discovered by user MattTheHit. An example of the file is available here.

Much of the promotional material shows scenes that simply do not appear in-game, specifically the nuclear trailer and the red band trailer showing scenes such as;


 * Venom Snake walks through a burned village and falls to his knees, shouting loudly.


 * A scene with Kaz and Venom Snake gazing at one another in the basement of Camp Omega.


 * A prisoner is beaten and then executed in an overgrown portion of Camp Omega's prisoner area.

As well, the tagline "From Zero to Omega " was displayed prominently in promotional material. The going theory is that due to the two games being initially developed alongside one another for a single game, they must be connected somehow for the solution to the final puzzle.
