Blastcraft
Blastcraft is a mod that focuses on reinforced walls in feel with the old voltz mod.
About this Mod
As of the 1st of June 2025, all future updates for ampz mods will require Voltaic API, and not Electrodynamics, in order to function. This update affects all the mods and brings world breaking changes, which are written in the changelogs. Note that this should however not corrupt your world. If you have such issues reach out on our discord channel!

Blastcraft intends to protect against the destructive forces in the ICBM mod. Each block available in Blastcraft can withstand a direct hit from a Missile. It is useful in the field of construction of missile-proof buildings, i.e. bunkers and military bases. Not only does it protect you against your enemies, but it also protects your home against the likes of test explosions or nuclear reactors.
This project is based upon Voltaic and requires this mod to run.
