Just how dangerous is the night time, players? That's what originally pulled me to this game - the night time switch up, and flashbacks to games like STALKER/State of Decay where getting caught in the wrong place at the wrong time can lead to ruin (avoiding emissions in the former, getting stuck in the woods without a gun in the latter).
Will be disappointed if they're weak sauce that you can survive quite easily. Will be happy if they're tough enough to force you to sneak/run to safety.
A) you will need to sneak. The super zeds show vision cones on the mini map, so that helps.
B) they're are lots of places where of your flashlight is off, it's almost pitch black and you can't see anything.
C) there are safe houses littered around that you can race for when things get hairy. They will get hairy.
