This simple mutator/add-on re-implements the concept behind SidDoyle's Dark Doom, using ZScript. Basically, makes Doom darker by reducing the light levels across all sectors in the map. A settings menu is provided to adjust the effect.
Please note I consider this project feature-complete and I will not be implementing any further feature suggestions at this time.

I'm leery of adding too many settings. Part of my hope here is to keep things simple and avoid kitchen sink customization. As-is I feel five CVars is pushing the limit for a reasonably simple mod.
That said, I've received requests for customization of origin, spread, intensity, color, and lookspring. I'm considering that some of these could be combined into some basic presets, like the following:
Cheap Incandescent (dimmer, warmer, wider spread)
Midrange Halogen (more-or-less as current)
Tactical LED (white beam, narrow focus, wide spill)
Handheld (springy, origin at player's chest) (as current)
Shoulder (below and to left of viewpoint, smoothly follows with slight delay)
Helmet (above viewpoint, very little movement delay)
That would only be two more CVars and I think covers most of the possible ground for what this mod would be used for. Thoughts? Ideas welcome. In the meantime, I'd like to give a shoutout to Steve's Flashlight Mod if you absolutely need in-depth customization.
