It looks like Fallout 4 is going to have a multiplayer mode if the reports and rumors are to be believed.
4Chan users have uncovered a document allegedly belonging to Sony and that document contains details about upcoming games and Fallout 4 was included in the document. The document lists Fallout 4 as an "online multiplayer" game.
While Bethesda is known for singleplayer games, it is not farfetched to think that Fallout 4 may have some online features as almost every game nowadays have a type of online multiplayer in it, even Bethesda's own Elder Scrolls series are now dabbling into multiplayer waters with the Elder Scrolls Online.
Meanwhile, Reddit user GNR_Informant revealed that Fallout 4 is already in the makings for the PC, PS4 and Xbox One.
The informant claims that he knows Bethesda's public relation officer and shared with the site, Motoring Crunch, on the content coming from the insider.
"First and foremost, the game will take place in Boston, and be kind of a direct sequel to Fallout 3 with a few groups returning. From what it sounds like, "The Institute" is pretty much the downtown DC or New Vegas of this game. Boston is going to be unlike anything we've seen in a Fallout game before, with buildings more on par with cyberpunk and retro-futurism."
"Androids play a big part in this game. The railroad from Fallout 3 is a faction. The enemies of the railroad is "the Plantation" - a group who force Androids to farm so that Humans can get food. The Institute is highly advanced and probably obtained or built their own GECK to start a farm."
"Due to complaints about using Super Mutants and the Brotherhood of Steel in Fallout 3 excessively and going against the lore too much, Bethesda has decided to avoid using these groups. Bethesda wants to make a new "race" (think Ghoul, Super Mutant) which will be central to Boston. Bethesda is currently looking at Lovecraftian fiction since Boston is around 'Lovecraft Country'."
"Bethesda has no plans to reinvent the leveling up system to make it more like Skyrim and want to make Fallout 4 more distinct from Skyrim since of the complaints that Oblivion and Fallout 3 were too similar. Bethesda is thinking about introducing a system, similar to Skyrim, where your skills can level up if you perform certain tasks."
