An adult-oriented sandbox, Parasite Black features a grim and foreboding fantasy setting. Taking place on the planet Mirnos, which is being attacked by an alien race known as the Demorai. You were born into the Alderaian kingdom and given a mission that was supposed to be fatal. But, instead, you've been given a do-over, which may be seen as a blessing or a curse. But with your new "gift," you might be able to shift the tide of war and save the realm from the Demorai's grasp!
