Shadows of Greg Mod 1.12.2 is a working update of Gregic Additions. It has been updated to work with modern versions of GregtechCE. This was necessary as Gregic Additions itself was abandoned, and the fixes included in GTCE meant not updating was impossible. GA is licensed under the LGPLv3, and SoG is licensed under the GPLv3. This modification and relicense is allowed by the terms of the LGPLv3 Section 2. This mod is a GregTech Community Edition addon, and requires it to run.
Shadows of Greg contains all features in GA that were not added directly to Gregtech.
