You are standing in an open field west of a white house, with a boarded front door. There is a small mailbox here. Curious, you open the mailbox, which reveals a leaflet. You take the leaflet and read it.

The leaflet reads,  "WELCOME TO ZORK! 
"ZORK is a game of adventure, danger, and low cunning. In it you will explore some of the most amazing territory ever seen by mortals. No computer should be without one!"
