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 territory is yours: you keep the level completion and its Intel and Alloy rewards, and your best records for that level never go down. From version 1.1, though, if your base falls during a bonus wave, you forfeit every bonus wave you cleared that run, along with the bonus income, Energy Cores and rating they earned, and that run's base-integrity income bonus, even in the first bonus wave. Extract at the bonus-wave choice to bank them.

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.

Does Frontier Siege use Game Center?

Optionally, from version 1.1 on iPhone and iPad. If you are signed in to Game Center, your scores and achievements appear on Apple's leaderboards; if you decline, the game plays exactly the same, fully offline. Game Center needs an internet connection; the campaign never does. To sign out, open the Settings app › Game Center. Reset Save in the game erases your local progress but does not remove scores or achievements already recorded in Game Center. The Windows version has no online features.

How do I delete my data?

Your game progress lives on your device — deleting the app removes it permanently, and we hold nothing on our servers. The one exception is optional Game Center on iPhone and iPad: if you signed in, your leaderboard scores and achievements are held by Apple, not by us. Manage or remove them in Settings › Game Center and your Apple Account. See the Privacy Policy for details.
