Something like a mix of base building and FPS action/horror. Like Fallout4 base building with STALKER athmosphere, during the day you would explore and gather useful materials then come back to the base before nightfall and put those resources into upgrading the base for defenses, like walls and turrets, then at night there would be an (increasingly difficult) assault on your base. You find the survivors and get them to join your base, they also give you quests and such. You'd also fight during the night along with your base dwellers, as an FPS action. I can elaborate more if interested.
