Zone K is the final stage of Dariusburst. It takes place in a fleet. A large enemy appears soon when the planet appears, which resembles an anglerfish. When it's defeated,the player flies into a ship,and walls will appear,which kill the player on touch,there are also turrets,which is REALLY annoying,it is best to focus on turrets and other large enemies that shoot bullets. Soon,the mechanical anglerfish appears again. Then the player flies out of the ship and another planet is in the background. A few seconds later,yellow mist appears and the warning message for Great Thing appears. The background changes to clouds and Great Thing reveals itself.
In Another Chronicle, Great Thing is replaced by Dark Helios.
