A few more details have been given about the upcoming Doom game, although I warn you now, they're just as vague as the original ones. They did confirm one major factor “There's going to be big guns, lots of blood and demons.”
Which let's face it, is indeed what we look forward to in Doom games. The game will still be built on id Tech 5. They aren't really sure on the story line just yet or what the name of the game will be.
Hollenshead did state that, "The goal for the game is that it will be the best game of its ilk when it's released.” They also are striving that the game not only hold true to the rest of the Doom games, but be innovative while it's at it. The game will be under the direction of Kevin Cloud.
