- TRIVIA -

This game was inspired by the actual 'Comet Halley' (pronounced HAL-lee). It was named after 'Edmund Halley', who calculated its '76-year orbital period'. Comet Halley was visible in 1910 and 76 years after, in 1986 (Feb. 9 exactly), just the year when this game was released by Taito :). Its next perihelion passage will be in 2061.

- TIPS AND TRICKS -

* Space Humour? : When you start a new game and after the RESCUE THE EARTH FROM THE COMETS ! message appears, you can move your ship over it. The text will get erased, and the following message will appear over it : DO NOT ERASE.

* Level Boss Trick : Shoot all but one of these squares and then press the hyperspace button (the smart-bomb) when the final square is lit. You should now receive 1,000,000 points! (this works for all level bosses).

* Another Tip : When the game is in Game Over mode, you can actually control the ship at one point. This is rather useless, but fun!
