In the dark night,
you stand in a dimly lit corridor.
Hide in the room and lock the door.
They know you're there. They will keep knocking on the door.
But never, ever open the door.

▶ Meet six survivors.
I don't know if they knew each other or if they were enemies.
The important thing is that each of them has their own survival method.
If you with them, you will be the only one who can survive.

▶ Collect essential survival items, skill cards.
Enhance basic abilities and strengthen facilities.
You can also build special towers.
You can also launch attacks that will confuse all enemies.

▶ Be careful in the last minute.
The appearance of those who come to find you doesn't seem normal.

▶ Multi-mode
They will come relentlessly and knock on the door.
Even if you fail, your colleagues will support you.
