Open Settings in the game, or the cheat mode offer screen, and tap RESTORE PURCHASE. Make sure the device is signed in with the same Apple ID (App Store) or Google account (Google Play) you bought it with.

An invulnerable player and base, skip stage, destroy all enemies, a tank upgrade, an extra life, enemy AI off, and a Test Range stage. It is a one-time purchase, not a subscription.

Stages played with cheats still unlock the next stages, but they don't record scores. You can switch cheat mode off or on at any time in SETTINGS.

Purchases are handled by Apple or Google, and we can't issue refunds ourselves. For the App Store, go to reportaproblem.apple.com; for Google Play, use your order history in the Play Store or Google Play Help.

Open MULTIPLAYER. On one device choose HOST GAME, on the other JOIN GAME. The joining device looks for the host on your Wi-Fi and connects.

• Same Wi-Fi. Both devices have to be on the same Wi-Fi network, not one on Wi-Fi and the other on mobile data or a different network.
• Local Network permission (iPhone, iPad, Mac). Go to Settings → Privacy & Security → Local Network (on a Mac, System Settings → Privacy & Security → Local Network) and turn it on for Tank Battle: Firefall City, then open the game again.
• Guest and public networks. Many guest, hotel and office networks use client isolation, which stops devices from seeing each other. Try your home network, or a personal hotspot that both devices join.
• Join by IP. If the host still doesn't show up, use JOIN BY IP and type the host device's IP address.

iPhone, iPad, Android devices and Macs with Apple silicon can all play together, in any combination, as long as they are on the same Wi-Fi.

No. The devices find each other with Bonjour and talk directly over your local network. Nothing goes over the internet and there is no server in between.

Open the .cotcampaign file (or a single .cotstage) with the game: tap it in Files, in Mail, or when it arrives by AirDrop, and choose Tank Battle: Firefall City. A campaign is added to your campaigns, a single stage to MY STAGES. You can also use IMPORT FILE in the game.

Use SHARE for a campaign, or SHARE STAGE and tap a stage. The share sheet lets you send the file by AirDrop, Mail or a messaging app, or save it to Files.

Campaign and stage files are JSON. A file that was edited by hand or cut short in transit may not open. Ask for it to be sent again, or write to us and attach the file.

On a touch screen, use the joystick to drive and the fire button to shoot. The game also works with a keyboard and with game controllers.

The game is in English, Czech and Russian. Change it in SETTINGS → LANGUAGE.

No. There are no ads, no analytics, no accounts and no tracking, and your progress stays on your device. The privacy policy has the details.
