Sources claim development is "not going well" although Bethesda and id Software remain strong behind its project.
"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," Bethesda's marketing boss Pete Hines said in a new statement.
"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."
This good news comes with some heavy baggage as Zenimax has cancelled RAGE 2 and "downsized" its future DLC releases for the original because of poor sales.
Now, all id staff are working on Doom 4.
I loved RAGE. It had a great atmosphere and design that was conceptually synonymous with id software. I believe RAGE failed because of poor marketing and a cluttered release window. It was a solid FPS but ulimately it was too grand of an idea and felt empty at times.
