Xbox Wire : Mistfall Hunter is set in a ruined world following Ragnarök, the aftermath of an epic war between Supreme Gods and Outer Gods. Nearly all deities have perished, their blood turned into the corrupting Gyldenmist, a fog thats sweeping across the land and distorting souls, driving the remaining beings in the world into madness and mutation.
