Modpacks get no grade of their own, so we show the grades of its mods. Of its 286 graded mods, 228 are graded A or B, 52 C and 6 D to F. Its last update came out 5 months ago, for Minecraft 1.20.1. See the mods
Factorio Nuclear +ONLINE is a Create-centered modpack built around a long industrial progression, with guided quests and custom recipes that make processed materials and production chains central to advancement. Players can automate ore extraction, farming, metal casting, fluid handling, fuel refining, and machine assembly, scaling from small workshops to large factories with diesel, steam, electric, and nuclear machinery. Its reworked material system unifies resources such as steel, bronze, zinc, sulfur, lead, and tin, with steel serving as a key industrial resource and rubber and crops given broader roles in progression. The pack adds Create-focused tools and machinery alongside Create Big Cannons, Scorched Guns, aircraft, drills, backpacks, and advanced storage, with many upgrades requiring specialized components and processed alloys. Exploration supports the factory progression through expanded terrain, caves, structures, dimensions, mobs, and loot, including Alex’s Caves, Alex’s Mobs, Incendium, and Regions Unexplored. Farming content includes Croptopia, Farmer’s Delight, and Mechanical Botany, while Thin Air, Spelunker’s Charm, Hordes, and Progressive Difficulty add survival pressure and tougher encounters.
Written from CurseForge . How we write it
The mods of its newest release (Minecraft 1.20.1 · Forge, 8 Jun 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 31 May 2026 for the same platform, Minecraft version and loader. We do not compare the versions of the mods yet.
No harmful code found in the projects we checked
We checked 288 of its 289 projects and the files in the pack itself.
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.
10 mods send something about you
We read the code of 275 of its 276 mods.
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 named in 4 of the 239 mods we checked
We found an AI tool named in them, or their authors declare AI content.
16 other mods show AI use only from after this release (8 Jun 2026), so it does not apply to the versions in this pack.
37 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.
