by jm360
Spectrum78 is a NeoForge spin-off of the Broken Script horror mod, built to bring back mobs that were cut from its development.
What it does
Spectrum78 restores unreleased mobs that were removed during the development of Broken Script, and adds further creatures tied to their own biological phenomena. Its new mobs and biomes appear in the world alongside the existing content, and the mod expands the lore around them. Because it runs on the NeoForge loader, it is installed in the mods folder like any other NeoForge mod.
The mod requires Geckolib, and the author advises a current Geckolib build to avoid crashes and collision issues. Spectrum78 runs on the client and the server, so both sides need it. Its files cover the single version 1.21.1, with the latest NeoForge build being 1.3.1, and it is released under All rights reserved, so it is not open source. The author describes its compatibility with TBS as working without friction, and translated introductions in Simplified English and Simplified Chinese are provided.

Use cases
Exploring a Broken Script world

Who it’s for: Players of Broken Script on NeoForge 1.21.1 who want the cut mobs and lore back, and server owners who run that game for their players.
How it compares
The Broken Content is also NeoForge for 1.21.1, client and server, and released under All rights reserved, so it is not open source. Default's TBS Addons targets the same loader and version, client and server, under the ISC License, which is also not open source. The Broken Script Extension and The Broken Array use the same loader, version and environment, with All rights reserved and no open source license.
