Japan, overrun by AI robots and autonomous drones. Your smartphone becomes your survival kit.
▶ Run an evacuation drill on the real map (J-Alert, tsunami, flood) / SANCTUARY MAP
In 20XX, Japan is overrun by AI robot units and autonomous drone swarms. The two factions are enemies of each other and fight in the streets. You are just a human. No gun, no EMP. All you have is a smartphone and a talent for hiding.
The twist: your phone's real sensors are the game mechanics. Shake your phone and robots sense the vibration. Speak loudly and the microphone picks it up — drones incoming. Clamp the phone to your chest and hold your breath, and you genuinely disappear. Switch to airplane mode and you really go dark to radio tracking.
Accelerometer (DeviceMotion) / microphone loudness (getUserMedia + Web Audio, on-device only) / compass (DeviceOrientation) / Vibration API / Battery Status API / network state (navigator.onLine) / Wake Lock / Fullscreen API / Web Share / localStorage / PWA (offline play, add to home screen).
The enemies are fiction, but what the game teaches about drone sensors, radio, heat and shelter is drawn from reality. Every INTEL card shown in play is collected here. Labels: FACT = repeatedly confirmed in public reporting or official guidance; ESTIMATE = based on today's technology and may change within years; FICTION = a game-only premise that does not hold in reality.
This is not a training manual and does not replace official instructions. In a real emergency, follow Japan's Civil Protection Portal, your municipality and J-Alert first.
Microphone input is used only to compute a loudness level — never recorded, stored, or transmitted. Geolocation is opt-in and only shown in your local combat log. Scores are stored in your browser's localStorage. Privacy policy (Japanese).
All robots, drones, and wars depicted are fiction and unrelated to any real organization, country, or technology.
