Mercurius Mod for Minecraft 1.12.1/1.12


Mercurius Mod 1.12.1/1.12 is a newly created analytics mod for Minecraft. Its author describes it as a very simple, transparent and open tool which is fully working on the latest version of the game. I can say that it is also really lightweight. It took a lot of time and hard work for Mercurius, its author, to develop it. It fully allows the community to openly gain inside into the versions of Minecraft out there. Moreover, the mod strictly respects Snooper settings. It also make possible mod integration for other mod makers to send in their own data. Moreover, this mod is free to use in any modpack and that’s a pretty good news.
