A derivative of
Gradius and
R-Type, only less fun.
The intro sequence appeared on the Genesis / MD version, and may have appeared on the Turbo CD / PC Engine version. The arcade version featured very little in terms of story; however, it was not without its own misspellings. In the demo scenes, vulcan was misspelled as valcan. Unfortunately, I know of nobody who's played through any version to get see the ending sequence, which I'm sure contains just as many hilarities as the intro.
The intro has to be seen to be believed, and there is an animated GIF roaming around the internet. Just in case you don't want to find it yourself, here's the full text:
IN A.D. 2101
WAR WAS BEGINNING.
CAPTAIN: WHAT HAPPEN ?
MECHANIC: SOMEBODY SET UP US THE BOMB.
OPERATOR: WE GET SIGNAL.
CAPTAIN: WHAT !
OPERATOR: MAIN SCREEN TURN ON.
CAPTAIN: IT'S YOU !!
CATS: HOW ARE YOU GENTLEMEN !!
CATS: ALL YOUR BASE ARE BELONG TO US.
CATS: YOU ARE ON THE WAY TO DESTRUCTION.
CAPTAIN: WHAT YOU SAY !!
CATS: YOU HAVE NO CHANCE TO SURVIVE MAKE YOUR TIME.
CATS: HA HA HA HA ....
OPERATOR: CAPTAIN !!
CAPTAIN: TAKE OFF EVERY 'ZIG'!!
CAPTAIN: YOU KNOW WHAT YOU DOING.
CAPTAIN: MOVE 'ZIG'.
CAPTAIN: FOR GREAT JUSTICE.
end.
Note: I've now seen the ending. Unfortunately, there's no dialogue to describe 'WHAT HAPPEN !!' after the final boss was defeated. Instead, you get 14 or 16 California Raisin lookalikes that dance around the screen for about 20 seconds. Figures.
