Steel Sky (Missile Intercept) is an independently developed casual defense game: waves of incoming missiles close in on your city, and you tap to fire interceptors that destroy them on a direct hit. Earn coins to upgrade turrets and skills, and hold the line wave after wave.
How do I play? Tap the screen to launch an interceptor toward that point; a direct hit destroys the incoming missile and refills ammo. Clear a sector's waves and defeat the mothership to advance; spend the coins you earn to upgrade firepower and unlock skills.
In-app purchases & billing? The game is free to download and offers optional purchases such as "Remove Ads", "Coins", and "Starter Pack", billed through the Apple App Store. Review them under Settings → your Apple ID → Subscriptions / Purchase History.
Ads came back after Remove Ads? On a new device or reinstall, tap "Restore" on the store page to restore "Remove Ads".
Too many ads / consent settings? Ads are served by Google AdMob; on first launch in regions such as the EEA a consent dialog appears, and iOS also asks whether to allow tracking (you may decline).
Data & privacy? No account or login required; the game itself collects no personal data. See the Privacy Policy and Terms of Use below.
For any problem, bug report, or suggestion, email apple@jikker.net and we'll get back to you as soon as possible.
