This BFG edition incorporates a version of the popular and necessary 'duct tape' mod, the PC gamer's answer to the original's insistence on a clear line between torch and gun - you couldn't use both at the same time. Here you can, and it's a wonder id ever released the game without this option.1
The chief advancement ... is the addition of the so-called "duct tape" mod, that allows players to wield a weapon while the flashlight is on. The original Doom 3 kept the flashlight as a separate item, meaning you had to plunge the world into total darkness if monsters suddenly attacked while you were exploring a lightless area. The "duct tape" mod became so popular among PC users for improving the overall experience that it was -- thankfully -- included in this HD remake.2
Is there an option to disable the now default "duct tape" mod, so as to imitate the original Doom 3 settings? This is a common question under reviews, but I haven't seen it answered thus far.
