In 2020, an unused level was discovered in the PC version of the game called Ruins of Joy Town that was meant to be played after The Goblin Fort level, but before Joy Castle. The unused level appears to be mostly completed, but lacks background music.

Part of the song "Promise," from Silent Hill 2, can be heard in the music that plays during The Dark Trail Ruins level. Both games were developed by Konami, and both were released in the fall of 2001.
