GregTech New Horizons, usually shortened to GTNH, is a long running quest based Minecraft modpack that rebuilds progression around GregTech, IndustrialCraft 2 and hundreds of other mods. Its voltage tier system, inherited from GregTech, moves players from low voltage through medium and high voltage to extreme voltage and beyond. Sounds tied to that stage became shorthand online because reaching EV takes hundreds of hours in the pack. Clips are shared in streams, base tours and edits as a quick, recognisable marker of late game tech progress.
