Fans on Reddit have already decoded the Morse code: CQ CQ CQ DE OZ PSE AS. This means ‘Calling any station, calling any station, calling any station, this is/from Oscar Zulu Please Stand by.’ There’s a station in Fallout 3 called Oscar Zulu, but no-one knows if it is related so far.
Some redditors think that the site has credibility as no-one has taken it down. If it was fake, developers Bethesda would likely take it down as copyright infringment. Also, it emerged over the weekend that Fallout 4 had been trademarked in Europe, although this isn’t always a reliable signal.
It’s possible the site is an elaborate hoax, but it seems to have been registered by Zenimax Media, which owns Fallout 3 developers Bethesda. It is widely expected that the Bethesda would move on to Fallout 4 after development of The Elder Scrolls V: Skyrim was completed.
The Fallout is a post-apocalyptic open world role playing series. The first game was released in 1997, with the last game, Fallout: New Vegas coming out in 2010.
