DefenseTech is built upon the Mekanism libraries, and as a result, the core module of Mekanism is required for DefenseTech to run, which can be downloaded here.

DefenseTech requires Minecraft Forge to load.  Simply drop the DefenseTech jar file into your “mods” folder to install, and you’re good to go!

Note: DTDK (DefenseTech Development Kit) is intended for use by developers and should not be used alongside the other modules.


For legacy downloads, please visit the legacy downloads page.

Any donation amount of at least $5 gives you your very own, high-tech MekaCape! This will be visible to you and all players on servers which have Mekanism installed.
