• Shooting the asteroid will cause a astronaut to appear. Touching this astronaut will engage a bonus mode. In this mode, the enemy ships will stop firing for 10 seconds and each enemy destroyed will earn the player bonus points.

• To take full advantage of the bonus mode, avoid shooting enemy ships for about the first 20 seconds of the wave until the asteroid appears and you activate bonus mode. This will allow you to kill more enemies while in bonus mode.

• Don't forget to use your warp button - it can get you out of some sticky situations. You have 3 warps per level, and warps do not carry over to the next level.

• An extra ship is awarded at every 100,000 points, but be aware that the score rolls over after 1,000,000 points.
