Many people have said night time isn’t that dark and night vision isn’t that useful from what I’ve heard. It’s useful in the woods but out in an open field you can spot people easily and navigate. I think the game should be almost pitch black at night to really encourage survivors to look for night vision more, and for survivors to use flashlights when they find them. I never see anybody use flashlights because they can see just fine at night. Flashlights are only useful in the bunker on Livonia when you don’t have night vision. Otherwise they are never used.
