An alternative would be to make the world really rotten, and use a quality distortion shader. When modern games show flames or heat, they distort the scene more or less randomly, to show that moving air. If you pretend the world of Doom is pretty much a rotten corpse, you could make the air visually stink, to the point that you can see fairly clearly up close, but in the distance things get all smogged up and distorted. As a side effect, it almost makes the player want to drop the distance between them and what they see through the distortion, to get a better view (be it to use, or to kill).

Pic shows a quick and dirty example from a different genre. Notice the distortion of the rear of the car, due to exhaust heat.
