In an evil world of magic and mystery you have been given a challenge! You must enter the darkness of the dungeons, a realm of unknown depth, where hoards of evil creatures abound, intent on only one thing - your destruction. Ghosts, Demons, Grunts, Lobbers and Sorcerors will make your life a misery, but Death will make your life hell!!
You must fight to stay alive, making use of the items within the dungeons: Keys, doors, magic potions and amulets and much more. Food scattered about will keep you healthy, but beware, some has been poisoned - look carefully before eating.
The object of the game is to survive for as long as possible against the onslaught of the enemy legions and to score as many points as possible.
