This is an endless game in which you try to survive against increasingly tough waves of enemies.

Each wave is longer than the previous one and with each wave enemies get tougher and spawn more quickly. Later waves also contain additional enemy types.

The higher the wave, the higher the score you gain from destroying enemies.
