In a world where you couldn't get to the ground floor, in a world where you were trapped on skyscrapers with insane murders with masks. Who can you trust? Because who was left to trust?

But you don't know how to find him, you don't even know if he's still alive.. it's only been a week since the call was cut out after hearing his voice. But you haven't found a single living person. Just masked psychos! You were resting when you saw a woman with two pistols crossing a rope bridge to your rooftop
