Build automated machines and progress through a world made of stone.
Modpacks get no grade of their own, so we show the grades of its mods. Of its 203 graded mods, 165 are graded A or B, 36 C and 2 D to F. Its last update came out 6 months ago, for Minecraft 1.20.1. See the mods
EMC SubTerra Tech is a Stoneblock-style modpack centered on automation and progression through a sequence of technology and magic mods. You begin with only cobblestone and a tree, use a custom recipe to make andesite, then combine Create and Tinkers’ Construct to build Resource Cores that generate materials for progressing through other mods. The progression moves from Create into Ars Nouveau and Blood Magic, then Thermal and Industrial Foregoing, followed by Botania and Mekanism, before Extended Crafting provides a path toward creative items and the completion trophy. More than 650 quests guide the pack’s automation, custom recipes, and custom items.
Written from CurseForge . How we write it
The mods of its newest release (Minecraft 1.20.1 · Forge, 5 May 2026). Each check result is for the latest files of that mod, which may not be the version in this pack.
Compared with the release of 2 Apr 2026 for the same platform, Minecraft version and loader. Same mods in both. We do not compare the versions of the mods yet.
No harmful code found in its projects
We checked all 204 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.
5 mods send something about you
We read the code of 202 of its 203 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 7 of the 172 mods we checked
We found an AI tool in them, or their authors declared AI content.
9 other mods show AI use only from after this release (5 May 2026), so it does not apply to the versions in this pack.
31 mods are not checked yet.
1 mod can use AI in the game.
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.
