Do you remember that impressive Half-Life 2 mod where a chap replaced all the sounds with new versions he’d made himself with his mouth, lips, tongue, saliva, and perhaps other parts of his gastrointestinal tract? What a silly sausage! Now someone has done the same for Doom. Shotguns, rockets, growls, elevators: you name it, they’ve recreated it with their mouth. What could be more Doom-y than an offering of flesh and spittle?
