EA Games has released Darkspore for the PC.  In this game, players are fugitives of a race called the Crogenitors, who were masters of DNA manipulation.  They created super-warriors called the Genetic Heroes using their genetic manipulations.  After discovering "exponential DNA" (E-DNA) they learned that it was unstable and produced mutated abominations that become the Darkspore.   As a surviving Crogenitor, the player must reconstruct the lost Genetic Heroes and lead them to battle against the Darkspore.
