OlympusCraft Heavy includes most of the previous mods from OlympusCraft but adds over 50 new mods for those with a passion for Modded Minecraft. In this modpack players can explore cave systems that are filled to the brim with ores from mods such as Netherending Ores, Thermal Foundation or Industrial Craft. There is even a place for the players that enjoy sitting back as their ever expansive farms can automatically harvest themselves with the combination of Mystical Agriculture and EnderIO. Whatever your tastes are. This modpack has it. Enjoy!
