KKND is set in a twenty second century post nuclear war world where two
races of humanoids struggle for the control of the Earth and what little is
left of its resources. KKND Xtreme is essentially the same as the original
KKND game except that it adds more missions. You play one of two races: either
Survivors or Evolved. Each race has their own unique set of units with which
to fight. The game revolves around constructing buildings, gathering oil and
training and deploying combat units to accomplish a set goal.
