(Although I have to wonder how the USSD particle-beam satellites would
fare against those city destroyers . . . )

Let's see, shields holding... dispatching attackers... satellites destroyed

I am almost 100% sure that those shields would NOT hold up against 3 or 4 
particle beam sattelites.  Think about it, a beamsat is as powerful as the 
alien's primary weapon.  The aliens would have to destroy the sattelites 
before they got their ships under them...




If a city destroyer stopped over the Genom tower, would Quincy:
a) leave MegaTokyo
b) order the city destroyer destroyed
c) try to make contact
