About this project
What does Gregtech: Extended Chemistry Extended add?
Gregtech: Extended Chemistry: Extended
This is a fork of Gregtech: Extended Chemistry, which is no longer maintained.
Gregtech: Extended Chemistry (gtec) is an addon for GregTech CEu Modern that adds expanded processing lines for Platinum, Monazite, and Bastnasite. These new lines provide an expanded challenge for producing the Platinum Group metals and the Lanthanides.
Comparison to GT:EC:
- retain monazite, bastnasite & platinum chains (with fixes)
- keep compatible with changes in GTCEu Modern
- remove echo circuit / naquadah stubs which were never in a state to impact gameplay
