A thin line divides heaven and hell

You are Flynn Case. Along with 15 other people, you are trapped in a sealed building and forced to participate in a killing game.

Why are the streets outside empty? Who are these people, and why can't you remember anything? And who will be the first to succumb to the killing game?

It's up to you to uncover the truth and unmask the killers.
