Bio-Hazard Battle
During the first global biowar, a powerful retrovirus filled the planet Avaron with new and deadly forms of life. Only a few survivors remain in O.P. Odysseus, an orbiting platform circling Avaron. Hundreds of years after the biowar, conditions on Avaron are still hostile but livable.
