Blind Fighting
I wear my sunglasses at night, in the sewers.

I think there should be penalties to engaging in combat in a dark environment. Such penalties that can be counter-acted by cyberware and various goggles accordingly. Thoughts?

This can start off as purely based around rooms with dark condition but be expanded to a penalty from being struck by attacks in eyes along with gas and flashbangs.

I love the idea. Would make turning off the lights in apartments make more sense too, for the ambushed or those hiding.

You click your flashlight into strobe mode and beat Bob's face in with the business end, blood flicking like rave confetti from his face.
