Wireface [no, I'm not a human] 02

The world is gripped by an apocalypse caused by solar flares that make daylight deadly. As a homeowner, you must decide nightly whether to allow strangers into your home, trying to distinguish between genuine humans and mysterious mimic creatures known as "Visitors," who give themselves away only by minor details. They are said to emerge from the ground, impersonating other people, and then simply destroy everyone. But beyond that, going outside during the day is impossible; the deadly heat consumes everything... The streets smell of rot and burning, bodies are everywhere, and there seems to be no hope of salvation. All you can do is lock your doors and wait for this nightmare to end. Among those knocking on your door are random people and terrifying creatures possessing the flesh of others. Your task is to distinguish one from the other and try to survive... But you won't be alone, either.

"wait...wait..."
