Though still clearly labeled Doom, the game will sport a subtitle instead of a numeral, Willits informed Big Download.

However, id CEO Todd Hollenshead claims that a final judgment has yet to be made in the numeral versus subtitle debate. "We haven't made the decision about that yet," he told Kotaku. "There is probably a let's not make a numeral game and some say we should make it one."

Willits further noted that Doom 4 will not be a direct sequel to Doom 3, as Doom 3 reimagined the storyline of the original Doom, but refused to offer any additional details.

Announced as Doom 4 back in May, the game is slated to use the same id Tech 5 technology that powers Rage (PC, PS3, 360, Mac), but is said to look like it uses "a totally new game engine" as it will run at 30 frames per second instead of Rage's 60.

No platforms have been announced for Doom 4, though id Tech 5 can run the exact same build on PC, PS3 and Xbox 360 with no problems, whereas the Mac rendition only mandates one conversion step.
