Los Angeles, the largest city in America, is attacked by aliens - first orange, and then blue. But this is not the worst thing. The worst thing is that they cannot be distinguished from ordinary people. Still, the city needs to be saved. Both the main character of the thriller and his friends understand this. Although... although each of them - and you, the reader, too - have a choice. Because this is not a simple horror film. It's a game. She will tell you what kind of person you are - smart or not very smart, cowardly or brave, a selfish person or a selfless person. And are you able to overcome your fear.
