Key & Compass presents:
The Horror of Goldmine City
by Gianluca Girelli

The Horror of Goldmine City is a Z-machine interactive fiction game written with Inform 6 and is © 2026 by Gianluca Girelli. This is episode 2 of Murray Shannon's saga, begun with The Seeds of Evil. It's also part of the BDB Project. This is an English translation and Inform port of the Italian 1987 game Murray Shannon: L'Orrore di Goldmine City by Bonaventura Di Bello.

In this sci-fi horror game, you again play as Murray Shannon. After saving the world from aliens in Creek Town, you set up a secret society to lookout for another invasion. A psychic alerts you to Goldmine City. There were reports of strange lights and sounds there before earthquakes all but wiped the place off the map. It's up to you to investigate.

This solution is by David Welbourn, and is based on Release 1 of the game.

SPOILERS AHEAD. Reading a walkthrough prematurely can sometimes diminish one's enjoyment of an interactive fiction game. Please make an honest effort to play the game before reading this walkthrough.
