An inside source tells Kotaku that id Software's Doom 4 is "postponed indefinitely." This news comes shortly after the release of id's first-person shooter, Rage, which allegedly has a lot to do with Doom 4 being put on the backburner.
According to the source, studio heads have "a serious lack of confidence in the project management at id," after Rage's reviews didn't quite reach their expectations (the Xbox 360 version currently has an 81 percent Metacritic rating).
Bethesda's Pete Hines has since Tweeted that "We don't comment on unannounced games and Doom 4 hasn't been announced," which doesn't exactly fill me with confidence that these rumors are entirely false. After all, Doom 4 was in fact announced to be in production on May 7, 2008. The fact that we've heard virtually nothing about the game since then isn't a good sign, either.
But as someone who grew up captivated by the original Doom, Doom II, and Quake, I sincerely hope this isn't true. Or if it is, I hope they return to the project soon.
