Doom 4 is the upcoming installment of the Doom series by id Software. The game is neither a sequel to Doom 3 nor a reboot of the franchise. It will use the company's new OpenGL powered id Tech 5 engine and was announced as in production on May 7, 2008, following speculation by John Carmack at QuakeCon on August 3, 2007.
Like Doom 2, it will take place on Earth, and will feature gameplay more akin the original Doom games rather than the horror styled gameplay of Doom 3.
On April 10, 2009 GameSpot published an interview with id Software's CEO Todd Hollenshead in which he revealed that Doom 4 is "deep in development." He stated however that the game is "not in pre-production". The development team is "relatively new" and id is "still actually hiring people" onto the Doom 4 team. GameSpot asked Hollenshead if Doom 4 is "a sequel? A reboot? A prequel?" and his response was "Gosh, that's actually an excellent question. It's not a sequel to Doom 3, but it's not a reboot either. Doom 3 was sort of a reboot. It's a little bit different than those."
On June 23, 2009, ZeniMax Media, best known for Bethesda Softworks, acquired id Software and announced that all future id Software games will be published by Bethesda Softworks, Doom 4 being one (in addition to Rage and future Quake titles).
During QuakeCon 2009, Hollenshead announced that there will not be any news released for Doom 4 until the next QuakeCon in 2010. Tim Willits did however talk to the press in May 2010 to boast that "it'll be even more awesome than Rage."
As of yet not much is know of the multiplayer in Doom 4, it has be said that it will have a much larger presence in that found in Doom 3. That said Carmack claims "Doom 4 multiplayer will not be as good of a multiplayer as Quake Live is, but it should still be good, and we will intend it to be better than Doom 3 or Quake 4 multiplayer,"
