Darkspore

Darkspore is a Windows video game based partially on the 2008 video game Spore. It is described as "a fast-paced, sci-fi Action-RPG in which the player battles across alien worlds to save the galaxy from the mutated forces of Darkspore." The game was released on April 26, 2011, for Windows. The Crogenitors were a race of unrivaled scientists and had built a large galactic empire. They had mastered mutation and used their knowledge to create an army of genetic heroes, that became known as "Living Weapons". But the discovery by Crogenitor Xylan of the E-DNA, an experimental amino acid that bonds to DNA, changed everything: it was used to weaponize life itself, and it was capable of achieving millennia of evolution in hours. However, the E-DNA was unstable and all of the subjects who came in contact with it were transformed into a genetic nightmare and connected with a hive mind known as "The Darkspore". The E-DNA rapidly turned into a virus that spread all over the galaxy, killing everything in sight. The end result was war. All genetic heroes were slaughtered, almost all Crogenitors were killed, and the Crogenitor empire dissipated star by star. Six surviving Crogenitors were put in cryogenic pods. Xylan was thrown into exile and E-DNA usage was outlawed. In his exile, he injects himself with E-DNA and becomes The Corruptor, master of the Darkspore. Five of the surviving Crogenitors were sent to planets with surviving genotypes, accompanied by the AI network HELIX, and tasked with constructing new Living Weapons untouched by Darkspore. The final surviving Crogenitor was left asleep indefinitely, awaiting the moment when the HELIX network had stabilized the E-DNA. After 1000 years the HELIX succeeded. The 7th Crogenitor was awakened and began to gather the new Living Weapons, strengthening them with the stabilized E-DNA.

Starting with only a few brave heroes, the Crogenitor Insurgency, as it became known, grew to the size of a small army. The Insurgency raided all Darkspore strongholds, discovering more comrades along the way. They grew ever closer to their ultimate goal of purging the Darkspore from the galaxy...
