I think an in-game gamma adjustment setting needs to be added. Or at least a calibration screen of some sort.
With the previous versions of Reforger, for me, nights got too dark, so I adjusted my computer monitor so in the darkest of nights I could just barely see. Just on the threshold to be able to see infront of me and not be stuck trying to navigate with a literal black screen.
