This is described as a real time interactive film - a grand name for a graphic adventure game. You guide Norman the warrior through subterranean caverns to find the Ba stone.
The use of a disc allows much more data to be provided than is possible with a cassette game, but the drawback is the lengthy delays while the notoriously slow disc drive chunters away. Every time you die, the first stage of the game has to be reloaded.
You wander along passages and through rooms, probing walls at regular intervals to discover secret rooms, and trying to avoid the guards, spider-like monsters and other hazards. Movement is controlled by joystick, but you can use the function keys to select four different modes: shield mode - where arrows don't inflict harm, arrow mode - to despatch armaments, fight mode, and take mode - for picking up objects.
It's quite challenging and should take a while to complete, but doesn't live up to the extravagant claims on the packaging. This game needs a disc drive.
