Doom (previously titled Doom 4) is a work-in-progress game anticipated to become the next release from id Software and their third game published by Bethesda after Rage and Doom 3: BFG Edition. Early planning and development began in August, 2007, and is currently ongoing. The game will be a reboot of the series, featuring settings and plot points similar to both the original games and Doom 3, and with art direction similar to the latter.
The new Doom is being built on a successor to id Software's id Tech 5 game engine which id Software is calling id Tech 6. Gameplay-wise the game is set to resemble the action-oriented nature of the classic Doom games more than the horror style of Doom 3.
QuakeCon 2014 finally saw a release of concrete information on the game after seven years of planning and development. While the actual live gameplay footage was restricted to QuakeCon attendees, various gaming press and individuals have made the following points of information available:
- According to executive producer Marty Stratton, who confirmed the game will be called "Doom" and is a franchise reboot, Doom will be "an origin game," and will feature "fast, FAST paced combat" that focuses on "amazing guns and blood and gore and gibs".
- There will be "unbelievable mechanical demons built through corrupt UAC experiments."
- id Software has apparently taken inspiration from Brutal Doom, adding the ability to stun and then viciously attack monsters in melee combat, even up to performing fatalities. In a page taken from the Doom Bible, the Doomguy is seen to rip an arm off a dead corpse in order to use its hand for biometric scanning purposes. Gun blasts and chainsaw attacks are capable of fully dismembering enemies.
- The game is now slated to target 1080p resolution at 60 frames per second.
PC Gamer tweets
- "First combat mechanic: demons. Mechanical, corrupt, hell knights."
- "Second mechanic: guns. Conventional guns, 'Big' guns..."
- "A key feature will be stunning enemies with a shot, then smashing their face with your boots."
- "Doesn't look like health regenerates. Enemies drop health when you squish them."
- In a manner similar to the alphas, information is displayed on the Doomguy's visor, replacing game-style HUDs. Monsters and items may be highlighted in real time.
- The player is acrobatic, able to effortlessly jump and perform parkour-like movements.
- Besides the chainsaw, the pistol, shotgun, super shotgun, rocket launcher, and plasma gun are confirmed to return, in addition to the Doomguy's devastating kicks and punches. Like most of their classic counterparts, the weapons do not require reloading animations.
- Monsters have been shown resembling the previous series' zombie, imp, revenant, and mancubus.
PC Gamer article on the reveal's purpose
According to Bethesda's vice president of press relations and marketing Pete Hines, Doom was not originally planned to be revealed until 2015, but citing an increasingly negative perception of id Software, they had decided to demonstrate what has so far been accomplished, to quell any doubts cast over the effectiveness of the id Software team and possibly detract claims of vaporware. The game will continue to undergo major development and changes, and a public reveal of the game is planned for 2015. 
In 2008, John Carmack stated that the game would have better graphics than Rage, but would be targeted to run at a lower framerate of 30 frames per second. id Software also intended to make Doom 4's multiplayer mode better than Doom 3's.
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 was "not [in] pre-production". The development team was "relatively new" and id was "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, Todd Hollenshead mentioned that id Software would reveal new Doom 4 information at QuakeCon 2010, between 12-15 August. However, during the event it was announced that there would be no news until the next year, as the development team was not ready to give a demonstration. Tim Willits did however talk to the press in May 2010 to boast: "it'll be even more awesome than Rage."
id Software technical guru John Carmack told OPM UK that anyone expecting to wait a long time for Doom 4 would have a shorter wait than first thought. Carmack told the mag the shooter should not take as long to get out the door, unlike Rage, which was announced in 2007 at QuakeCon, and would not be out until next year. Producer Tim Willits told VG247 the following in May: "Well we’ve got Doom 4 going on right now below our feet here. The Doom team are all sped up and working on this technology base – I’m not really at liberty to discuss much about it, but it’s going full steam ahead right now." He also added: "It shouldn’t take as long to ship as Rage. It’s already in the pipeline and we feel good about it."
On August 16, 2010, id Software CEO Todd Hollenshead apologized to Stephen Totilo of Kotaku for the game not appearing at QuakeCon in 2010, before mentioning that the game would be targeted for a simultaneous release on Windows, PlayStation 3 and Xbox 360, saying "That's absolutely what we're thinking."
At Quakecon 2011, prior to the release of Rage, John Carmack stated that once Rage shipped, the id Software development team would move to Doom 4 to speed up the project. Since then, Rage had indeed been released, although no further information on Doom 4's development became available.
On 28 February 2012, some alleged screenshots were released on Official Xbox Magazine UK's website, but the images were discredited by id Software's creative director Matthew Hooper via Twitter by saying, "Those images have nothing to do with what you're gonna see in Doom 4. When we officially show things, you'll see awesome."
2013 Kotaku article
In April of 2013, Kotaku published an article describing Doom 4 as trapped in "development hell". Citing connections to id, the article claims that Doom 4 has suffered under mismanagement, and that development was completely restarted in 2011. Inside sources described the pre-2011 version, which was to portray the uprising of Hell on Earth, as heavily scripted and cinematic, comparing it to the Call of Duty franchise. The pre-2011 version was criticized as mediocre, but the sources also described the new version as "lame" and a "mess". 
2013 Staff departures
Starting in June 26 with the abrupt resignation of Todd Hollenshead as company president and accompanying resignation from the ZeniMax Media board of directors, incumbent id Software staff began to depart the company at an increasing rate. By November, John Carmack, who had earlier reduced his role to technical advisor, departed the company entirely to focus on work at Oculus VR as its Chief Technical Officer. The majority of the id Tech engine team is believed to have followed him, based on statements made by departing employees and allegations leveled against Oculus by ZeniMax Media in their lawsuit filed later in 2014.
2014 Beta testing
In late February of 2014, Bethesda offered advance beta testing access to a product they are currently simply calling "DOOM", using a flat-shaded variant of the familiar logo, along with pre-orders of Wolfenstein: The New Order. The offer is explicit in mentioning that the product is not yet ready for testing and that those taking part in the promotion will be contacted later when the testing begins. It was eventually clarified that the beta access is per platform (ie., the version of Doom to be tested will be for the same platform on which Wolfenstein was purchased), and that the platforms currently targeted for release now include Microsoft Windows, Xbox One, and PlayStation 4.
Further details or information have yet to leak from anyone participating.
Bethesda and id unveiled a "Doom" teaser at E3 in June, 2014, containing footage of a monster that may be the new incarnation of the cyberdemon gearing up for battle as a female narrator laments the corruption of a promising new technology (likely teleportation) into a gateway for the demons. No actual gameplay footage is featured in the teaser, however. This was accompanied by the launch of a new official website at doom.com, and the promise of a more detailed reveal at the 2014 QuakeCon.
As of July 2, 2014, Bethesda amended their previous press release to "clarify" that the reveal would be exclusive to QuakeCon attendees, and would not be broadcast or allowed to be recorded for outside exposure. The reveal took place on July 17, at which time the convention's Twitch stream was shut down. A live game play demonstration followed, which was reported on in detail by convention attendees.
It was at one time possible that Doom 4 would be a remake of Doom II, or would otherwise be set on Earth. Todd Hollenshead made a statement which arguably supported this speculation at the time. The comment was as follows: "Doom is part of the id Software DNA and demands the greatest talent and brightest minds in the industry to bring the next installment of our flagship franchise to Earth".
A series of concept screenshots of the game were leaked by a former employee as part of a portfolio which seemed to confirm the "Hell on Earth" theme. While Bethesda eventually acknowledged that these were indeed screenshots of what was then Doom 4, they were also quick to add that they were from an earlier stage of development and no longer represented the current state of the project. Information made available at QuakeCon 2014 seemed to put this rumor to rest, as Earth-like environments have been shunned in favor of Martian bases.
