Halley's Comet Game Cheats
Submitted by: rickHH
In the game, each level consists of two parts.
In the first part, you fly in space. In the second
part you are, what appears, inside a spaceship. At
the end of this part, there is a "level boss"
consisting of flashing squares that fires at you.
Shoot all but one of these squares and then press
the hyperspace button (the smartbomb) when the final
square is lit. You should now recieve 1 000 000 points!
As far as I know, 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!
