Metal Gear Solid-skaberen Hideo Kojima har allerede erklæret, at det kommende Ground Zeroes fungerer som prolog til Metal Gear Solid V: The Phantom Pain, men nu har han også uddybet størrelsesforskellen på de to spil.
I en besked på Twitter (oversat af Siliconera) forklarer Kojima, at The Phantom Pain vil være "hunrede gange større" end prologen.
"GZ is both a prologue to the MGSV story and, at the same time, a tutorial for a new MGS, which transitions to sneaking simulator. With that said, GZ has a relatively small field as compared to the main game (which is hundreds of times larger) without time zones changing in real-time. However, each mission offers different time zones with different playstyles."
