When Chuck first meets Bryce at Stanford in 1999, they find they have a lot in common. Both of them are engineering majors, and have the same taste in games. Chuck shyly admits that he's planning to make his own version of the classic text based game Zork, which Bryce, another big fan of the game, agrees to help him build on a TRS-80 computer.
When years later, Bryce sends Chuck the Intersect files, stolen in Chuck Versus the Intersect, he uses their version of Zork as a password to open the email that contained the Intersect database. The terrible troll and hero's satchel are unique to Chuck and Bryce's version and do not exist in the original, but the nasty knife does.
Real Zork Edit
Zork is a text based video game which was one of the first interactive fiction computer games and an early descendant of Colossal Cave Adventure.
