FIELD SUPPORT

Where can I get Frontier Siege?

Frontier Siege is out now for iPhone and iPad — download it free on the App Store. It requires iOS 15 or later.

How much does it cost?

Frontier Siege is free to download and play. The game contains no ads and no in-app purchases.

Do I need an internet connection to play?

No. Frontier Siege runs entirely offline — the whole campaign works with no connection at all.

Where is my save data stored? Can I transfer it?

Progress is saved locally on your device. It isn't synced to the cloud yet, so it can't be transferred between devices — cloud save is on the roadmap. Deleting the app deletes your progress.

How do territory income and starting currency work?

Every level you win becomes a territory that produces campaign income. Your performance — difficulty, base health, wave clear rate, economy buildings protected, bonus waves survived — sets its output, and a share of your total campaign income is added to the starting currency of future missions. Replay old levels to raise their income.

I lost during bonus waves. Did I lose everything?

No. Once you clear a level's required waves, the victory is locked in. Falling during bonus waves only costs you part of the extra bonus income you were fighting for.

What devices and ages is the game for?

Frontier Siege is designed for iPhone and iPad in landscape orientation and is rated 9+. It runs at 60 FPS on recent devices and 30 FPS on older hardware.

How do I delete my data?

All game data lives on your device — deleting the app removes everything permanently. We hold nothing on our servers. See the Privacy Policy for details.
