The Demon King Kull has constructed a machine allowing him to inject the souls of the most insidiously evil demons imaginable, into the bodies of mechanical warriors of his own design. With these robotic demons, these so-called Robodemons, he's holding the Earth in a death-filled grip of terror as he does the vilest things imaginable.
A nameless, masked warrior comes forth armed with his mystical boomerang, jetpack and suit of armor, ready to free his people and their world by destroying the Demon King and his Robodemon factory in the farthest reaches of Hades. In the role of this anonymous hero, you'll have to pass through seven levels of pure evil to reach your goal, spanning from the first level of bone, to Demon King Kull's own lair, all of which happen to be populated by the most vile creatures you can imagine.
Starting in the level of bone, you'll use your jetpack to fly through a passageway constructed of bones, reaching a graveyard and battling calcium-fortified foes, such as leaping skeletons, projectile-spitting crossbones, and rolling skulls. And this is merely the beginning, as you'll fly through passages leading to six other levels, wielding only your mystical boomerang in defense.
From the bile pools and arteries constructing the level of flesh, to the captive souls of your ancestors you must free in the level of condemned souls, you definitely have your work cut out for you. The other levels are the level of fire, level of demons, the Robodemon factory and finally Demon King Kull's lair, where your final battle awaits.
And simply reaching the exit of each level and waving goodbye is definitely not on the menu; a demonic boss guards every level's exit, so you better snag those heart icons and extra lives in preparation.
