Bethesda has confirmed that development on Doom 4 has been restarted after the original build failed to live up to expectations.
In response to a Kotaku report that suggested that Doom 4 was "in trouble and is far from complete," Bethesda PR man Pete Hines issued the following - and quite telling - statement.
"An earlier version of Doom 4 did not exhibit the quality and excitement that Id and Bethesda intend to deliver and that Doom fans worldwide expect."
"As a result, Id refocused its efforts on a new version of Doom 4 that promises to meet the very high expectations everyone has for this game and this franchise. When we're ready to talk about the Doom 4 Id is making, we will let folks know."
It's likely that Doom 4 will make its debut on next-gen consoles and PC, and receive a graphical overhaul.
According to the Kotaku report, development was restarted in 2011, described as both a 'technical and creative reboot,' with no two developers agreeing on whether the game should focus on balls-out action or horror (John Carmack was reported to have stood up and announced that "Doom means two things: demons and shotguns."). RAGE 2 has also allegedly been shelved, which will annoy practically no-one whatsoever.
As ever, watch this space, and don't hold your breath.
