In 1977, a text-based adventure game was released. Zork is a text-based adventure game wherein the player explores the ruins of the Great Underground Empire. The player types text commands for their character to traverse locations, solve puzzles, and collect treasure. The game has hundreds of locations, each with a name and description, and the player’s commands interact with the objects, obstacles, and creatures within them. Commands can be one or two words (e.g., “get lamp” or “north”) or more complex phrases (e.g., “put the lamp and sword in the case”). The command must fit the location’s context (e.g., “get lamp” works only if a lamp is present). The program acts as a narrator, describing to the player their location and the results of certain actions. If the game does not understand the player’s commands, it asks for the player to retype their actions. 

Nearly 50 years later, multinational power management company, Eaton, has developed the Server Room of Doom, where you navigate the game and if you are good enough, you will earn the “Raider of the Lost Password” award.
