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
ending of horrible death without newton gravity:the sun explodes digging into the planet destroying south city and making a sand volcano hollowing the lanet and the oil reaches the south city and ignighting everything
Most of the time, the planet implodes.
