Help with your defence.

Getting started

1. Hold your iPhone horizontally and follow the short tutorial.
2. Choose SENSOR, then tap the map to place it. Its coverage reveals nearby threats.
3. Choose INTERCEPT, then place an interceptor where its weapon range overlaps your sensor coverage.
4. Tap START. Combat runs automatically. Review the result and adjust your defence for the next attempt or wave.

Placement and coverage

Tap an existing unit to select it, drag to move it, or use the delete button to remove it during preparation. The SENSORS and EFFECTIVE overlays help you inspect detection and engagement coverage. Unit costs and the remaining budget appear beside the map.

Stopping or restarting

ABORT WAVE returns you to preparation. The menu offers level and campaign restart with confirmation, and lets you switch between classic and pixel-art graphics.

Progress and offline play

The game works offline and saves campaign progress on your iPhone. If you close the app during combat, reopening it returns to that wave’s preparation with its starting base health, budget and defence layout. There is no account or cloud sync. Deleting the app removes its local progress.

Sound and language

Check your iPhone’s volume and silent mode if you cannot hear the game. The interface supports English, Russian, German, French, Spanish and Brazilian Portuguese, according to your device’s language preferences.
