A OneBlock survival pack filled with lurking creatures and jump scares.
Modpacks get no grade of their own, so we show the grades of its mods. Of its 34 graded mods, 22 are graded A or B, 7 C and 5 D to F. Its last update came out 10 months ago, for Minecraft 1.20.1. See the mods
One Terror Block turns the classic OneBlock survival setup into a horror experience, where breaking blocks can yield resources or bring new dangers while you progress on a single island. Its threats include The Man From the Fog, From The Fog, Eyes in the Darkness, Cave Dweller Reimagined, The Silence, and other creatures that stalk, watch, chase, or attack unexpectedly. Disturbing environmental audio, dark psychological atmosphere, jumpscares, and sudden encounters build tension, while more dangerous combat makes survival harsher. The pack supports both singleplayer and multiplayer, with the OneBlock map installed separately.
Written from CurseForge . How we write it
The mods of its newest release (Minecraft 1.20.1 · Forge, 27 Dec 2025). Each check result is for the latest files of that mod, which may not be the version in this pack.
3 files not listed: no matching project found.
No harmful code found in the projects we checked
We checked 34 of its 35 projects and the files in the pack itself, without running them.
Why we show this: a modpack installs the files of its mods, and each mod runs on your computer like any program. Our checks look for known signs of harm. They cannot prove that a file is harmless. In the grade: a modpack has no grade of its own, and each mod's result counts in that mod's grade.
2 mods send something about you
We read the code of 30 of its 33 mods, without running it.
Why we show this: a modpack runs the code of its mods, and a mod can send things about you over the internet, like your player name or your login. Contacting an address to check for updates or download files sends nothing about you. Not in the grade: sending data can be normal for what a mod does.
AI used in 2 of the 28 mods we checked
We found an AI tool in them, or their authors declared AI content.
5 mods are not checked yet.
Made with AI: not checked yet
We have not looked for AI tools in the pack itself yet.
Why we show this: some players and servers avoid projects made with AI, and AI in the game can send what you write to an online service. Not in the grade: using AI does not tell whether a project works well or is kept up to date.
