So on August 4th, a Reddit user by the name Ryuken777 on the Metal Gear Solid subreddit, published a full list of what seemed to be the full mission list for the entirety of Metal Gear Solid V:The Phantom Pain, however 5 days later, a user named Sicario1 also a Reddit user, posted a comment that is as follows:
While this was a rumor to begin with, it’s not hard to fathom that somebody would come up with something to fool people into thinking that they know info that everyone else does not, and Sicario1 is a good example of that.
Of course leaks like this do happen, some being legitimate, like achievements being leaked, details regarding gameplay or modes like the recent Halo 5 Guardians leak, or leaks like Grand Theft Auto V’s pre-order download being released way ahead of schedule by mistake, allowing the lucky amounts of people who got to download and install the game to their hard-drive because of a mistake, to leak game-play and such before it’s release date, so it’s no wonder that fans were lead to believe that it was true.
While reading through the mission list, it does seem believable, but when considering the facts, in all the gameplay demos, including the recent Gamescom 2015 demos of Metal Gear Solid V: TPP, most missions, and assuredly story missions, seem to be on a per mission basis, instead of a chapter by chapter basis, re-enforcing the sandbox look and feel of The Phantom Pain.
Regardless, this is why you take everything you hear with a grain of salt, and only believe in the facts, or else you’ll be dissapointed.
