About Subject 4471
SUBJECT 4471 is a single-player, first-person sci-fi horror game built around stealth, exploration, and survival inside an AI-controlled research facility. You wake with no memory of who you are. A number identifies you. Cameras follow your movements. Beyond the glass, the experiments are still running. Search for supplies, recover access permissions, and uncover the truth behind the facility as you work toward shutting down the intelligence that controls it. STAY OUT OF SIGHT Mutated researchers roam the corridors. BOT-4000 security robots scan for unauthorized movement. Somewhere beyond containment, the biological weapon S10000 is listening. Watch patrols, listen for approaching threats, and choose when to move. Hide inside cabinets or restroom stalls, and use branching ventilation routes to reach another part of the facility. MAKE EVERY BATTERY COUNT Your flashlight and motion detector depend on battery power. Search drawers and cabinets for replacement batteries and medical kits. Manage your inventory and decide when visibility, information, or healing is worth using your supplies. BRING THE FACILITY BACK UNDER CONTROL Restore cooling equipment, reset security circuits, and expand the permissions on your employee card. Each sector brings different systems to operate and new obstacles to navigate. Deep in Zero Ground, cut the main supply and cross a machinery-filled power hall to reach the remote restart controls. With the lights out, yellow emergency beacons and distant movement become your guides. DISCOVER WHAT SUBJECT 4471 MEANS Explore laboratories, surveillance rooms, sealed chambers, and industrial machinery. Piece together records and environmental clues to discover what happened here—and why the facility will not let you go.Read more
