Specific request in relation to the IU

I was really expecting there to be shadow/flashlight mechanics that stop, end a side not especially horror, but where you can’t see anything, and therefore stress.
As in this single player game OVERWHELM on Steam of course not multiplayer, I would love to have torch bugs, UI user interface that doesn’t work anymore, an anxiety inducing environment where visibility is difficult.

Also, would it be possible in several extensions to power the others? With pvp like in l4d2, Evolve, etc?
