North, East, and West city ave nuke silos. They filled them up with bombs before realizing that those would explode. As the oil began to catch fire, South city built a wall to keep their oil. The wall broke twice, but was fixed. However, the metal around the oil deposit melted and closed off most of the south's oil supply. They got by for a while, once raiding the ruins of East city before the oil got into their water supply.
my version: in a nuclear war, a lightning bomb is detonated that destroys the planet.
in my version,the world runs on deuterium but the tech deprived bottom city forgot and they invented a neutron deuterium drill and everyone died
In my version North and East cities are centres of power, with East being slightly more powerful. West town usually rebels and gets destroyed, resulting in a war between South and North for their oil port.
My version: A giant meteor impacts the planet, igniting the oil, making the planet explode.
in my version aliens place a few specks of molten sing and destroy the planet
In my version, South City bombs the greedy West City, so the other cities can live in peace. But a decade later, the problem struck again. So South City, having turned against them slowly, drops and experimental virus on North City. The virus grows uncontrollably, and in a day, the whole planet is covered in virus. By then a group of people from each city are in space, and they use soap against the virus. But when the virus is killed, the cities are destroyed.
XD trololman_inc that is awsome as crap nice find !!!!
ending with newt grav. the sun explodes sending a gravity wave and shattering the planet so only space citys survived untill the oil reached them it ignighted and killed them all
