After a nearly four year hiatus, the Doomseries is back. Id Software today announced that Doom 4 has officially begun production and that the company is looking for new talent to produce the sequel. Said id Software CEO Todd Hollenshead, "Doom is part of the id Software DNA and demands the greatest talent and brightest minds in the industry to bring the next installment of our flagship franchise to Earth." Right now that's all we know. No platforms have been announced but, given the franchise's history, we'd expect it to show up on the 360 in some form.
Those looking to scratch that Doom itch while we wait for more info may want to check out the new series of Doom 3 novels. The first in a planned trilogy, Worlds on Fire, is actually pretty decent (yeah, we were surprised too).
