Fallout 4

Fallout 4 is an upcoming game planned to be developed by Bethesda Game Studios and published by Bethesda Softworks.

Setting
The confirmed setting is in Boston, Massachusetts; this confirmed from the trailer released on June 3rd of 2015. It shows the Statue of Paul Revered and the USS Constitution in the trailer as well, along with the State building of Massachusetts with it's unique Golden Dome.

The setting will also include mountains and the outlands of Boston's city limits, also Boston contains tall skyscrapers unlike Fallout 3 and New Vegas.

Another piece of evidence is that you can see the Bunker Hill memorial in the first trailer and Fenway park.

Development
Initially, in 2004, Bethesda Softworks licensed from Interplay Entertainment the rights to create and publish three Fallout games (Fallout 3, Fallout: New Vegas and Fallout 4). Later, in 2007, Bethesda purchased the entire franchise, and Interplay licensed back from Bethesda the rights to a Fallout MMORPG. The legal dispute is now over, with Bethesda Softworks and its in-house development studio retaining the rights to all of the Fallout franchise, including an MMO.

In 2008, Bethesda's Pete Hines said: "The whole reason we went out and acquired the license and that we now own Fallout is that we clearly intended to make more than one." He also added: "This is not something we're going to do once and then go away and never do it again. When that will be or how long that will be God only knows, but we acquired it specifically because we wanted to own it and develop it and work on it like we do with The Elder Scrolls."

Release date
In August 2010, Todd Howard revealed in an interview with Eurogamer that Bethesda was working on two projects; one had been in development for two years (beginning after Fallout 3 was released), and the other was still in pre-production. It is now known that the title farther along in development was The Elder Scrolls V: Skyrim. There is still no confirmation on what the second game is.

On January 9, 2013, the voice actor behind Three Dog (Erik Todd Dellums) was given permission by Bethesda to hint towards his appearance soon. On his Twitter account, he stated, "To all my #Fallout3 and #ThreeDog fans: There may be more of the Dog coming! Fingers crossed!" However, in July of the same year, Dellums tweeted that the game he is working on is not being produced by Bethesda Softworks, therefore it was not the anticipated new Fallout title.

On April 15, 2013, Bethesda Game Studios announced on Bethlog that they had completed all new content for Skyrim and were moving the studio's attention to an as of yet unknown title that had previously been in pre-production. Although Bethesda Softworks did announce The Evil Within during the same week, this is being developed by another studio and will have no direct impact on whatever project Bethesda Game Studios is currently working on.

On February 18 2014 Todd Howard was interviewed on Rock paper shotgun, and said that a new game announcement would be very far away. "We don’t [have a timeframe for our next game announcement]," he said, "but I think it’s gonna be a while." He is forever positive and says "PC is resurgent," enthused Howard. "Skyrim did better than we've ever done on PC by a large, large number. And that's where the mods are. That feeds the game for a long time. And it's exciting that the new consoles are very PC-like. That opens up avenues for us going forward to do things that we've wanted to do in the past. There are kind of random ideas we're working on right now, and it's like, "Wow, I think there's potential here to do some really cool stuff."

On June 2, 2015 a countdown timer was set on Bethesda's Fallout website expiring on June 3 at 10:00 AM EDT.

On June 3, 2015, seconds before 10:00 AM EDT, the Fallout 4 trailer was released on Youtube.
