GregTech 5 Unofficial (sometimes referred to as GT5U) is a fork of GregTech 5 created open-source by Blood Asp. It was originally created because GregTech 5 was incompatible with Forge version 1335 and up, but later versions of the mod reintroduce many of the older machines and generators from GregTech 4.
