Publisher's blurb Explore an ancient Martian city while you prepare for your escape. Your ship crashed on the Red Planet and you have to get home. You will have to explore a Martian city, repair your ship and deal with possibly hostile aliens to get home again. 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. Author's blurb This is highly recommended as a first adventure. It is in no way simple - playing time normally runs from 30 to 50 hours - but it is constructed in a more "open" manner to let you try out adventuring and get used to the game before you hit the really tough problems. User summary Originally developed for OSI systems, the game later was ported to a wide variety of home systems.
