Atomic Ragnarok

In an alternate universe where the Cold War actually lead to the detonation of the Nuclear bombs by the USA and the Soviet Union, the Earth was destroyed by nuclear fallout.
  Four hundred thirty eight years into the future the vestiges of humanity live deep underground, and technology has grown immensely...
  Unfortunately, corruption rules and near anarchy reigns under a government that cares only for its own advancement and neglects its people only until an opportunity arises. Crime sweeps the subterranean streets and evil experiments run in the darkness.
  In chaos with no law, mercenary groups pop up as the only thing keeping the populace from total Ragnarok...
  ...and maybe, just maybe it’s time to turn this system on its head.
