How to Play

Defend your base

Shoot the announced multiples. Survive each wave with at least one launcher standing. If all three launchers are destroyed, the game is over.

Aim, select and fire

Tap or click a numbered ship to fire. Shoot multiples of the number shown and let the others land. Each of your three launchers carries five missiles.

Keyboard: Left / right selects a ship; Space fires. A, S and D select launchers. P pauses.

Crystals and shields

Untouched non-multiples land in the bays and give crystals. Five crystals add a shield charge; ten rebuild a destroyed launcher without a shield. A shield absorbs one hit. When all missiles are gone, landing ships give half a crystal.

The game pauses while these instructions are open.
