Publisher's blurb Fast moving excitement on the bottom of the sea. Adventures are interactive fantasies where you give the computer plain English commands (i.e., "take the sword", "look at the control pane") as you explore alien cities, space ships, ancient pyramids, and sunken subs. Average playing time is 30 to 40 hours in several sessions. There is literally nothing else like them - except being there yourself. User summary Intended for any OSI compatible system
