Mangtech is a large tech pack that I have designed to be extremely difficult and long. It has been modeled after Project Ozone 2 and FTB Ultimated Reloaded. It has a huge variety of mods that you are almost completely required to get as far in as possible. Among these are Industrial Craft 2, Ender IO, Tech Reborn, Thermal Expansion, Mekanism, Nuclearcraft, Mystical Agriculture, and Applied Energistics 2.
Please enjoy!
Note: This pack is still experimental and has not been tested much. Please notify me if you find any huge exploits or points that are impossible to get past!
