Bethesda Softworks, a subsidiary of ZeniMax Media and publisher to such titles as The Elder Scrolls V: Skyrim and various Fallout titles, has once again shot down rumors that Doom 4 has been cancelled. All Games Beta recently published an excerpt stating the game had been cancelled in addition to revealing several leaked screenshots that originally appeared on 4Chan.
In a statement to Joystiq, Bethesda vice president of public relations and marketing Pete Hines said that Doom 4 isn't cancelled and that when they are ready to talk about it and show it off, they'll let everyone know. All Games Beta has since added more screenshots to their gallery which now sits at 170 total images. It's up for debate at this point whether the artwork is actually from Doom 4 or perhaps another unannounced title or expansion pack.
Similar rumors were unearthed in October 2011 when Kotaku reported that sources close to the publisher tipped them off that the game had been "indefinitely postponed." Hines responded at that time stating that no games under development at id had been postponed.
Doom 4 was first confirmed by id Software on May 7, 2008 but since that time, little has been mentioned of it. The title took a back seat to id Software's first-person shooter Rage which was released on October 4, 2011 on multiple platforms. Rage received mixed reviews from media with some citing underdeveloped characters and a lacking storyline.
