Extended Night Vision Range
Night vision is extremely useful for scavenging and gaining an upper hand in surprise fights, but it doesn't help much for finding enemies. I'd really like to go do night combat, but I struggle to locate anything with only one hex of sight. It'd be cool if there was a night vision extension augmentation or a temporary drug that increased sight range at night.
In the meantime, is there a file I can edit to increase night vision to two hexes by default, or perhaps two when on a hill?
