Various concept art images purported to be from Doom 4 have made their way on to the Internet, courtesy of an anonymous poster on the 4Chan message board.
The same user has insinuated that id Software's long-awaited sequel has been cancelled, once again fuelling speculation previously quashed by publisher Bethesda.
"Doom 4 isn't cancelled," Bethesda's VP of PR and Marketing Pete Hines told Joystiq earlier today.
"When we're ready to talk about it and show it off, we'll let everyone know."
Bethesda as yet has not commented on the validity of the leaked artwork.
