The world is becoming more dependent on computer technology and no one thinks about what it could threaten humanity. And we decided to dream up a bit and imagine what would happen when a global virus paralyzes all systems. In Error # 54 this has already happened and you are the main character here - a very skilled hacker. Only you can destroy the virus and save the world from man-made accidents and a complete apocalypse. But the problem is that you were kidnapped by the villains who are not interested in the prosperity of our planet. You are in a building with a single dim bulb in the hallway with many doors. Find a flashlight and try to find a way out.
