You are the incident commander. A threat actor has breached your network, the clock is running, and every action costs something. Zero Day Command is a turn-based cyber defense strategy game about making good calls under pressure: investigating before you act, containing the attacker before critical systems fall, and telling the public the truth at the right moment. HOW IT PLAYS • Each turn runs through Intel, Analysis, Action and Resolution. You spend action points on eight commander actions: Scan, Trace, Isolate, Restore Link, Public Notice, Patch, Honeypot and Restore Node. • Balance three resources: Public Trust, Continuity and Evidence Quality. Evidence Quality (Low, Medium or High) decides which actions are safe and which public statements are credible. • The threat actor adapts. It shifts tactics as the mission goes on, from initial access through lateral movement to exfiltration. • ARIA, your on-device analyst, observes the board and reports in incident-response language. She tells you what she sees, never what to do. • Every mission ends with an after-action report on how you handled it. WHAT'S INSIDE • A 15-chapter campaign. Chapters 1-10 are free. Chapters 11-15 are a one-time purchase you can restore any time from Settings. • A Daily Incident: a new scenario every day at midnight UTC, the same for every player, with a streak counter. • Field Operations: procedurally generated scenarios. • The mechanics follow the incident-response lifecycle in NIST SP 800-61. GOOD TO KNOW • No ads and no subscriptions. • ARIA runs entirely on your device: Apple's on-device model on iOS 26 and later, and a built-in library of reports on iOS 18 to 25. • Progress syncs through iCloud. Game Center is optional and only connects if you turn it on. • Requires iOS 18.0 or later. Runs on iPhone and iPad. ## Is Zero Day Command safe?

A run with too little evidence to score no longer extends it. • The debrief and ARIA's analysis now describe a failed closure as a failure instead of a success. • The mission screen header no longer wraps or cuts off the turn counter, resource values and evidence badge, including on narrower screens. • Game audio now starts up in the background. ### 1.0.2 — 2026-10-26 Ten more campaign chapters, a fairer Daily Incident, and a round of gameplay and sound fixes. • New free chapters 6–10: Zero Trust, Living Off the Land, Double Pivot, Insider Threat and Supply Chain. • Chapters 11–15 are available as a one-time purchase: Ghost Protocol, Cascade Failure, Red Team Active, Attribution Crisis and Operation Endgame. Restore it any time from Settings. • The Daily Incident now resets at midnight UTC. Every player faces the same incident and the same attacker that day. • The main menu shows a countdown to the next Daily Incident, and streaks are counted per UTC day. • New board animations when a system is compromised, a route is isolated, a honeypot is triggered, data is stolen and the mission ends. • Action effects now play on the board when you Scan, Patch, Restore or deploy a Honeypot. • Threat activity now moves along the network routes. • Trace now reveals hidden clues on the system you trace. • Patch no longer works on a compromised system. Use Restore instead. • Undo and the turn limit now behave correctly, and Undo also removes the action from the turn log. • ARIA's debrief now reflects the actions you actually took. • Field Operations credits now sync correctly across your devices. Credits you spend on one device no longer come back on another. • Game sound now follows the silent switch and no longer lowers music from other apps. • Settings has separate volume sliders for music and sound effects. • The background music no longer clicks when it loops, and unmuting brings it back. • Starting a new operation now asks before discarding the one in progress. • Shared results show the mission's name. • Game Center connects only if you turn it on. • The privacy policy now covers iCloud sync and Game Center. ### 1.0 — 2026-10-25 No release notes. ## More apps by Andre Couture - [Map Telemetry](https://appshunter.io/ios/app/map-telemetry/id6760446001) - [TAK Can App](https://appshunter.io/ios/app/tak-can-app/id6762517940) All apps by Andre Couture: https://appshunter.io/developer/1421131837 --- *Data collected daily from the US App Store and indexed by [AppsHunter](https://appshunter.io/).
