Five planets, ten passes each. Clear a pass to open the next one; clear all ten to land on the next world. Twenty lives per pass — every leak costs you.

Tap a glowing pad to raise a turret. Four kinds: Laser Battery (single target), Ion Lance (ignores armour), Missile Battery (splash, ground only), Deflector Field (a fixed energy wall that stops ships on the lane).

Click a built turret to upgrade it up to level 4 or sell it back for 60% of what you spent. Call waves early for bonus gold — the fleet gets heavier every wave.
