The aftermath of a devastating alien attack against a huge city complex, in an act of desperation the inhabitants used weapons of mass destruction on their own city to deter the invading forces. The weapons did indeed repel the attack, the ships that weren't destroyed or to damaged left retreated, the huge alien ships that were caught in the resulting explosions smashed into the cities bellow, huge towering wrecks littered the cities, plumes of smoke and ash ran on for miles, most of the area was reduced to a fiery inferno. Those that survived were greeted only by hellish scenes and a hostile environment, they considered the ones who had died in the attack the lucky ones.
