From Wikipedia Infidel is an interactive fiction computer game published by Infocom in 1983. It was written by Michael Berlyn and was the first in the "Tales of Adventure" line. Due to Infocom's virtual Z-Machine, it was ported to a wide variety of popular computing systems of the day, including the Apple II and Commodore 64. It is Infocom's tenth game. The player's character is a self-styled adventurer and fortune hunter. As the game begins, the player awakens to realize that he has been drugged by his men, who have stolen most of the equipment and abandoned the camp. All the food and water are gone, and the player has no idea how to get back to civilization. He may very well have been left to die in the barren desert. But the navigation box finally arrives, convincing him that everything will work out as long as he can find the pyramid! Once he does, of course, there is the small matter of the traps the Egyptians set to protect their treasures from plunderers like him...
