(Discontinued / Obsoleted) Advancement Plus - Mekanism Extension
The (Discontinued / Obsoleted) Advancement Plus - Mekanism Extension is a retired add-on that once gave Mekanism players a full set of custom advancements to chase. The mod author has stepped away from mod development, so the project is no longer maintained, but its concept and structure are still worth understanding if you enjoy completionist-style gameplay or want to study how Mekanism progression can be turned into achievements.
What This Mekanism Extension Actually Did
This add-on was the second entry in the Plus Series. Its purpose was simple but effective: it added advancements covering the entire Mekanism family, including the standard Mekanism mod, Mekanism Additions, Mekanism Tools, and Mekanism Generators. Instead of grinding through machines with no recognition, players received in-game goals that tracked their progress through ore processing, energy generation, tool crafting, and late-game infrastructure.
The result was a mod that rewarded exploration and experimentation. Every new machine tier, every upgraded generator, and every specialized tool could trigger an advancement, which made long Mekanism playthroughs feel more structured. As the original description put it, it was a good mod to impress your friends, especially on servers where showing off a completed advancement tree was a point of pride.
Supported Versions and Loader Requirements
Before you consider this add-on, keep its technical limits in mind. The (Discontinued / Obsoleted) Advancement Plus - Mekanism Extension only ran on the Forge Mod Loader. It was not built for Fabric, Quilt, or NeoForge, and no ports were released after the author retired. It was designed around the Minecraft versions that Mekanism itself supported at the time, so it is tied to older Forge-based modpacks rather than modern releases.
There was also a hard dependency: the base Advancement Plus - Vanilla mod had to be installed for this extension to function. Without it, the Mekanism advancements would not register. The author used Java FML DataGenerators to build the advancement JSON files programmatically instead of copy-pasting raw files, which kept the data consistent across the supported Mekanism modules.
How to Install It in an Older Forge Profile
If you already run a legacy Forge instance and want to try the mod, the process is straightforward. Note that because the project is obsoleted, there is no official support, and you should treat any setup as experimental.
- Install a matching Forge version for your Minecraft release.
- Place the Advancement Plus - Vanilla file in your mods folder first.
- Add the (Discontinued / Obsoleted) Advancement Plus - Mekanism Extension file alongside it.
- Install Mekanism, Additions, Tools, and Generators to unlock the full advancement set.
- Launch the game and check the advancements screen to confirm the new entries appear.
This is the same how to install routine used for most Forge add-ons of that era, and it remains the only reliable method now that development has stopped. If you prefer a smoother route, the foxygame.net launcher keeps retired builds like the (Discontinued / Obsoleted) Advancement Plus - Mekanism Extension in its add-on catalog, so you can add it to a compatible profile without manually matching file versions.
Why It Was Discontinued
The author retired from mod development and thanked the community for its understanding. That decision left the add-on frozen in time. Mekanism continued to evolve, adding new machines and mechanics, but the advancement set was never updated to cover them. As a result, the mod is now labeled discontinued and obsoleted: it still works in the right legacy environment, but it will never receive bug fixes, new advancements, or compatibility patches.
For players who want a complete, current advancement experience, this extension is no longer the answer. For historians of modded Minecraft, however, it remains a neat example of how a simple idea, adding goals to a tech mod, can meaningfully change how a playthrough feels.
Final Thoughts
The (Discontinued / Obsoleted) Advancement Plus - Mekanism Extension is a snapshot of a specific moment in Mekanism's history. It required Forge, depended on Advancement Plus - Vanilla, and covered the four main Mekanism modules with custom goals. If you want to download (Discontinued / Obsoleted) Advancement Plus - Mekanism Extension today, do so knowing it is unsupported and version-locked. For anyone building a retro Forge pack, though, this (Discontinued / Obsoleted) Advancement Plus - Mekanism Extension for Minecraft is a small but memorable piece of the Plus Series legacy.
