No, they're not human.

🛑 Welcome to the Emergency Situations Committee monitoring system. You are the Block 7 Building Manager. 📅 Date: Unknown. 🕒 Time until power outage: Constant. What happened? The world as you knew it no longer exists. A few weeks after the Silent Fall, the skies turned gray, and things began wandering the streets. We call them Visitors. They look like people, they talk like people, but they are not people. Their goal is to infiltrate our last refuges. Your task, as the manager of block No. 7, is critical: LET PEOPLE IN. Survivors roam outside the block's walls. Cold and radiation aren't the only threats. There's also Him—a pale, thin man with empty eyes. He's killing those who remain outside. You must decide who to save. DO NOT LET THE GUESTS IN. If a Guest gets inside, they will kill everyone, including you. They are excellent at camouflage, but they are not perfect. Every day, the Emergency Situations Committee's Emergency News publishes new identified signs of Guests. Study them. Listen carefully to residents, ask questions, and look for inconsistencies. WATCH FOR SIGNS. Today, the Guest may not blink, tomorrow, they may repeat phrases, and the day after, their skin may be unnaturally cold. Signs change. Be vigilant. COOPERATE WITH THE EMERCOM. Every 72 hours, the Emergency Control Service (ECS) will take one of your residents for "examination." This is a mandatory measure to identify new signs of infection and maintain the safety of the unit. Do not interfere. ECS reports are your primary survival tool. Rules of survival: Listen to people's stories. Their memories are the key to verification. Observe their behavior. Are they too perfect? ​​Too nervous? Trust the Emergency Situations Committee data, but remember: even official signs can be inaccurate. Your terminal is your only connection to the world. Use it wisely. Remember: err on the side of a person, and you'll get a bullet from Him. Err on the side of a Guest, and you'll get a kick outside the door. The system is loaded. The first survivors are already knocking on your door. The decision-making falls to you. Good luck, Building Manager. Block #7
