I suppose somebody should provide the "real" translation of the Japanese dialogue here. Straight from GameFAQs.com:
The war began
Outside Ship - An explosion occurs.
Captain: "What happened!?"
Mechanic: "Someone detonated bombs all around us!"
Close-Up of Excited Communications Officer
Operator: "Captain! Incoming transmission!"
Operator: "Image coming through on the main monitor."
Captain: "You... you are...!!"
Close up of CATS
CATS: "You appear to be preoccupied, gentlemen." (sarcasm)
CATS: "Thanks to the cooperation of the UN forces, we've taken over all of your bases."
CATS: "Your ship too shall soon be destroyed."
Close up of captain & CATS
Captain: "Im.. Impossible!"
CATS: "We thank you for your cooperation." (more sarcasm)
CATS: "Enjoy the remaining moments of your lives...."
CATS: "Hahahahaha ...."
Close up of Forlorn Captain
Ship's Bridge (ZIGs on monitors)
Captain: "Launch all ZIG fighters!"
Shows a ZIG pilot powering up
Captain: "We leave it up to them..."
Shows a ZIG moving into launch position
Captain: "Give us hope for our future..."
ZIGs on monitors, Bridge Explodes
Captain: "We're counting on you, ZIG!!"
The ship explodes.
A lone ZIG zooms into view!
translated by WooJin Lee and two sheepishly anonymous persons.
...and, in case you couldn't guess, that lone ZIG fighter is being piloted by you, the game player.
And so the adventure begins....
