tank battle: firefall city

Terms of use

last updated · October 31, 2026

These terms govern your use of the Tank Battle: Firefall City game (“the game”), made by its developer, Alexej Penzencev (“we”, “us”). By downloading or playing the game you agree to them. If you don't agree, please don't use the game.

01The license

The game is licensed to you, not sold. If you got it from the App Store, Apple's Licensed Application End User License Agreement (the “Standard EULA”) applies; if you got it from Google Play, the Google Play Terms of Service apply. These terms add to them; where they differ, the store's terms apply. You may use the game on devices you own or control, as the store's usage rules allow.

02Free game and cheat mode

The game, with all 50 built-in stages, your own stages and campaigns and two-player games, is free to download and play.

Cheat mode is an optional, one-time, non-consumable in-app purchase. It adds an invulnerable player and base, skip stage, destroy all enemies, a tank upgrade, an extra life, enemy AI off, and a Test Range stage. Stages played with cheats still unlock the next stages but don't record scores.

• The purchase is made through the App Store or Google Play, at the price the store shows you before you confirm. It is not a subscription and never renews.
• It belongs to the Apple ID or Google account you bought it with. Use RESTORE PURCHASE in the game to unlock it on another device signed in with the same account.
• Payments, refunds and billing questions are handled by Apple or Google; we can't issue refunds ourselves. For the App Store, go to reportaproblem.apple.com.

03Your stages and campaigns

You can build, import and share stage and campaign files (.cotstage, .cotcampaign). What you make is yours. When you share a file, you are responsible for it: please don't give it a name or description that is offensive or that uses other people's work or trademarks without permission.

Files made by other people are not checked or endorsed by us. Import files from people you trust; we are not responsible for the content of stages and campaigns made by players.

04Two-player games

Two-player games run directly between two devices on the same local network; no account or server is involved. Play with people you know and on networks you trust. Network conditions, router settings and device permissions are outside our control, so we can't guarantee that two devices will always find each other.

05Fair use

You agree to use the game lawfully. In particular, you agree not to:

• copy, modify, resell or redistribute the game, or reverse engineer it except where the law allows;
• use the game, or files made for it, to disturb or harm other people or their devices.

06Your data

The game stores your progress and settings on your device only. The privacy policy explains it in full. You are responsible for keeping your own backups.

07Ownership

The game, its design, code, artwork, sound and built-in stages belong to us and are protected by copyright and other laws. These terms don't give you any right to our name, icon or other brand features. Tank Battle: Firefall City is an original game and is not affiliated with or endorsed by any other game or its publisher. Apple, iPhone, iPad, Mac, App Store, AirDrop and Bonjour are trademarks of Apple Inc.; Google Play and Android are trademarks of Google LLC.

08Warranty

To the extent the law allows, the game is provided “as is” and “as available”, without warranties of any kind, express or implied, including merchantability, fitness for a particular purpose and non-infringement. We don't promise that the game will be error-free or available at all times. This doesn't affect any statutory rights you have as a consumer that can't be waived, such as the legal guarantee for digital content in the European Union.

09Liability

To the extent the law allows, we are not liable for indirect, incidental, special or consequential damages, or for loss of data or progress, arising from your use of the game or your inability to use it. Our total liability to you is limited to the amount you paid for the game and its purchase. Nothing in these terms limits liability for death or personal injury caused by negligence, for fraud, or any other liability that can't be limited by law.

10Changes

We may update the game and these terms. When the terms change, we will update the date at the top of this page. If you keep using the game after a change, the updated terms apply; if you don't agree with them, stop using the game.

11Governing law

These terms are governed by the law of the country where we are established, without regard to its conflict-of-law rules. If you are a consumer, you keep the protection of the mandatory laws of the country where you live, and you may bring claims in its courts.
