No other details were given, but we're guessing it'll run off of id Tech 5 (or perhaps something greater). Given the ending of the Doom 3 expansion Resurrection was pretty conclusive, we don't know where the team will take the Doom story next. Our guess? Probably send a space marine to Hell to fight demons. Perhaps this time he (or she) will pack a better flashlight.
